Sir when you are uploading this video in Hindi language
Thanks Raul
can u make a separate video about semi-conductor
i am very much confused o this topic
so when u order, can u get thw components also from them?
@@mohammedsaad3503 jlcpcb has another company named lcsc. In the ordering section on jlcpcb.com, you can upload the BOM file, which contains the components that you need. In addition, you can order your pcb with the components soldered on them according to your schematic file.
Back in time, I became independent. I started my own business designing electronic test equipment, to test assembled PCB circuits. But I was so poor that I had to use freeware to do the job. I had to create PCB's in the process but the freeware PCB design software only allowed a limited amount of components. It also allowed you to create your own components. So I would design a portion of the PCB layout, and then due to having reached the maximum amount of components allowed, resistors, capacitors, transistors, etc, I created a new component which in truth was a combination of all the components used so far, and their specific layout. Yep, when you are poor, you find a way around everything. Anyhow, one company was so impressed with my work that they hired me full time. Eventually I was also designing high voltage power supplies for neon sings as well as designing the test equipment to test them at the assembled PCB level. Not bad for a grade ten dropout. I had no education in electronics, but was self taught.
Thanks for the inspiration
Use Kicad, it's free
@@ahmadwahyudin5196 he says back in time not now
@@akashghosh1151 oh sorry, my mistake
Your story resonates with myself. Having no grades doesn't mean your not capable achieving and learning to reach your goals.
This only means we have different learning pattern that schools don't teach. But it also means we are capable to find solutions faster by thinking out of the box.
Thanks for sharing your story and inspiring others. 👍
Holy crap this is the most impressive and comprehensive tutorial I have ever seen on youtube. The organization, the speed that you go from topic to topic, the thoroughness of the design, and software use even shipping? Incredible.
Love the way you explain everything and we get everything.
all greek to me
yep bc greek is my first language :)
Thanks to your video i was able to make my first actual circuit board! I didn’t do the fancy printed board thing but i had some blank pcb boards and was able to recreate this regulator as my very first circuit board! Im only 18 and have been interested in/ making electrical things (lights mainly) but your videos explain how components work and how to use them in real world applications. Thank you so much for putting the time into making your videos so well thought and so well explained. To help people such as myself follow their passions or dreams easily building circuits without having to go to school for it or destroying components trying to figure stuff out based on less helpful videos. Cheers! 🥂 🍻
I want to truly thank you for your videos , I am a french student in preparatory classes and you explained very well how electrical component (inductor ,capacitor ...) work with simple explication ( water tank...) you help us a lots (i just start the électromagnétism i wait your videos on it :) ).
This regulator project was amazing thank you and go on :)
Glad they help yoi
"Click Auto-route" is an on-going joke at my job. Worked out well for you though!
Where do you work? Pcb manufacturer?
@@michaeld9682 No, I work in product development and regularly have to review PCB layouts.
Sometimes on larger PCBs I'm working on I'll hit auto-route just to see how ridiculous it gets lol
hahahaha I laughed hard! Since the circuit is basic on the video, he did that ya know :)
@@jmannUSMC if you write your drc properly, auto route always works and saves me the pain of routing 100 components manually like a laborer when I have software provided edge
Thank you Engineering Mindset. I'm old but as much as possible , I maintain a good body shape and health just to learn electronics. I believed that here is no such thing as ' TOO LATE" for everything, but everything comes on the right timing as long as you want to learn.
I don't have the proper words to express how good this video is.

@@deansmith4752 why?
Me too
I implemented this project front to back with success, and fabricated Paul’s Gerber files, too. This video was so well put together.
i can only say THANKS, because the way you explain is so clear and rapid... Please continue to do projects like this because I have never undestand electronics faster!!
This tutorial on UA-cam is incredibly impressive and comprehensive. I'm amazed by how well-organized it is, the perfect pace at which you cover various topics, and the depth of detail in design and software use, even including shipping. It's incredible that you also provide resources for free; as a student, I find this incredibly beneficial. Thank you so much for this helpful content, and many thanks for your generosity.
ur such a good teacher man i learn so much so quick yet not in an overwhelming way you for sure have an invaluable skill
absolutely fantastic way to transfer knowledge, well done, so .... comprehensive. esp love the 'hey this might work too for this reason, but this is fine' element. teaches me so much more as it gives me a scale of the subject/component/concept
Excellent video. Love the design software and custom printed PCB. Back in the 80's when I used to play with electronics I either used the boards from Radio Shack with tons of holes, or I hand-drew a PCB and etched it myself with one of their kits.
Radio shack, miss that place
This is the best Electronics and Engineering channel on UA-cam. Without a doubt. All videos are clear, objective so as not to leave any "loose ends" that could create confusion. I was very happy to find this channel. Many questions that I have come here and resolve. That simple.
Thank you !🙏🙏🙏🙏🙏🙏
The best circuit designing A to Z using Altium I have ever seen on UA-cam 👍🏻👍🏻
The explanation was outclass. You motivated me to design my own voltage regulator like you did. Thanks man. God bless you
Designing a voltage regulator is not as hard as it seems. Especially, if you have a basic understanding of circuits and some electrical components. After watching a few online tutorials, I decided to give it a try. The end result was a functioning voltage regulator circuit that met my needs.
I must admit that I was motivated to design my own voltage regulator after watching one of your videos. Your explanation was outclass.
Best channel on the entire internet right here, it’s true. Always more to learn.
Buck and boost circuits amplify the complexity. I would love to see him do a vid on those
This is the BEST video you have ever made! I love all of your videos but learning to make your circuits a reality is the most amazing thing ever you have no idea!!!
To put it simply, you're brilliant!
Love the way you teach😍: first explaining circuit, then design, then using design app.
Very good, I hope you continue this way. 🙏
Hai bro I am second year electrical engineering student but never feels like I am studying electrical engineering
Just books books no lab is possible because of online teaching even if we have our lab practicals we don't have goodlab technicians so we just go there for grades but you are amazing thank you . by watching your videos now I think lab and electrical eng also intersting
Great job and I especially like the way you added the Altium tutorial in for the PCB design. I'm working with Altium now and it's a great help.
Thank you so much ! but we need more projects like this in order to apply what we have learned ! I think everyone agree on that :D
great tutorial. explaining the functionality of each component was the best part form me. thank you for sharing
Impressive explanation...7805 always remain the top priority and almost have one since 2010, when i first started my own design.
If you were my teacher in school, every student would be a genius
I'm an architectural engineer...but I love your work and way of explanation...Great work....
That was a brilliant video, I love that PCB design software. I used to do it by hand in the mid 80's and the tapework as well all by hand. We made the artwork twice the size so it was easier to tape then the original would be reduced to half size by copier then ready for printing to PCB. That was the best job I ever had, I even say that over 30yrs later. . All we were given was a circuit design from some big company on a piece of paper, I even had a small diagram on a piece of card. We had to design everything ourselves, I loved it.
I lost interest in computers years ago but I would love to learn that system you have there, its brilliant.
Good work 😊😊
I did it so in the 70th
This teacher is much better than my school teacher. Best electronic yt channel on youtube. Thank you.
Pretty cool video, you explain things so clearly. Electricity is so fascinating...
Dear God. That software tutorial was like learning German. Time for me to hire a tutor! Lol
Like eagle software
That software was just bad, I'm sure there are better ones that are more user friendly.
@@Othman1992on and don't cost an arm and a leg, like Altium
Paul thanks for everything. I have learned lots of useful things about my profession more than I learned from university. Your channel is AMAZING... and please make a video about solar energy systems🙏
I never knew how a voltage regulator worked before I started watching your channel. I also learned about linear regulators and how to choose the right one for a specific application. I now know more about my profession than I ever did from university. Thank you for making these videos!
you will learn how to make a 5V regulator using capacitors, LM7805 regulator and Schottky diode. This circuit works by converting the unregulated voltage from the battery into a regulated 5V output. The capacitors smooth out the voltage fluctuations, while the LM7805 regulator ensures a stable 5V output. The Schottky diode protects the circuit from reverse polarity connection and also increases efficiency.

You are the reason why I am so passionate about being an electrical engineer.
Great video, really i have get benefit of it. Next video we need overcurrent protection circuit .
Thank you so much for your exerts.
This is one of the best videos I've ever watched 🔥🔥. You killed many birds with one stone, by explaining different aspects in a way that makes the process seam easy, starting from components' operation, circuit design, to PCB fabrication. Lots of love for the great work you're doing.
Excellent video, very well explained and also entertaining ! Great job, well done !
This channel is awesome! I’m 34 and getting into Arduino. Your channel is very helpful in explaining the process as well as entertaining with new ideas and stuff. Thank you!
Nice videos, and also really well explained. Please continue making this kind of videos that really helps a lot to those who want learn something new the best vibes for you
In this video, we're going to take a look at a voltage regulator circuit. This is a very important circuit, and it's used to maintain a constant voltage output despite changes in the input voltage. This is useful for things like powering microcontrollers, or other sensitive electronics.
The basic principle of the voltage regulator circuit is simple. We have an input voltage, which is applied to the Vin pin of the regulator. The regulator then outputs a constant voltage on the Vout pin. This voltage is regulated by the feedback resistor Rfb.
The regulation of the output voltage occurs because of the way that transistors Q1 and Q2 are connected. Transistor Q1 acts as an amplifier, while transistor Q2 acts as a switch. When Vin is greater than Vout, transistor Q1 is turned on and transistor Q2 is turned off.

A small solar panel as the input voltage would be sweet.
Probably need a few solar cells, need to input +7V minimum, but it would work
Voltage regulators are inefficient and only work with higher voltage. Think of it this way "Where does all the extra voltage go?
@Joachim Shekelberg wasted electricity is never a good thing
@Joachim Shekelberg what circuit do you use , any linear regulator always have dropout votage
Not realy, this curcuit doesnt take advantage of a solar panel power changes trow the day
You are a brilliant mind 🧠 all the way from South Africa, much appreciated.
very inspiring, my guy just summarized my 4 yrs in high school that was spent in studying physics in explaining the fundamentals of electricity under 10 mins, as well as condensed my 5 years in campus that I spent chasing a degree in electronics under the pcb section as well as 2 extra years of entrepreneurship by taking us through the ordering system from jlcpcb. Ill never forget this degree of insult
This was a great video about regulating voltage with the 7805. I wonder if you are also going to make a video about buck converters or SMPS.
Plenty more coming
This is next level tutoring right here - if this kind of quality content existed when i was meandering my way through grade school, I would have had my seat firmly planted in those classroom benches instead of chasing dirty $kankz and booze 😂
You my brother, have the best explanations in the world. May you be blessed for life !
Thanks for the great tutorial, I just ordered the voltage regulator PCB and my students will be building them soon. Thanks again.
Buck boost modules vs regulator ics. Need a lecture on this
Great vid, I was looking for such a device, we have gas BBQs that I installed with micro solar panels to charge the igniter, I ran into a problem when the cloud cover changed to output voltage it would trip out the controller for the gas flow, I think this might be the answer to keep a constant voltage from the battery to the units circuit.
Thanks from downunder 🇦🇺👍

Guys, this is the quality! Thank you very much
glad i put this video in a favourites folder, this is exactly what i am needing to build, 5v and 10v versions with leds and switches, thanks
Great video! It would be great to explain to beginners the principle of why the values of those capacitors are used. Or else, you are just teaching someone to copy a design and not design it themselves.
used a 1.00uF capacitor instead of the 0.22 since i didn’t have one, still works perfectly. Powered with a 9V battery and output is 5.01V as desired. Made a similar circuit before without a diode and with only 2 capacitors instead of 4.
You can connect DC to a 7805 directly, no need for any extra components, those are just recommendations, but I've only ever used it on it's own and a battery for any logical gates circuits, which can only work with 5v.
@@Freixenetynt yes i know. the capacitors just help filter out any noise in the circuit
You're best teacher I've ever seen, please continue and make a video about more complex PCBs...regards
Excellent video, very talented at breaking down terms that an average tech can understand!
There should be a heatsink attached with the voltage regulator though.
Remember that W=V*I. Meaning, if you have higher voltage input (say 24V) but output is only 5V and you're drawing only 0.2A then the linear voltage regulator has to dissipate about ( 24V - 5V ) * 0.2A = 3.8W as waste heat. It will get quite hot quite fast. Times like that - consider if buck regulator would be better option, if not for the noise/EM interference that accompanies it.
I would turn the voltage regulator 90 degrees and place it near edge. Another possibility would be placing it flat on the other side (there are more options). It all depends on how you are planning to connect it to the heatsink and/or how much heat you need to dissipate.
Based on the datasheet, at 25°C ambient, you can draw 6.58W. That's 1.32A. Keep in mind that's at 25V. If your input was 12V or 9V, which is typical, you can easily achieve 1.5A without a heat sink. However, I would use a heat sink to dissipate heat through a sealed case to reduce heat building up, which might affect other components.
Belíssimo! Show de bola.
Incredible video ... i am not an engineer but i watch these videos .. because i really love it. Thanks for posting them. 🤗
Your videos are incredible as always!
For polarity protection, I'd use small bridge rectifier. Then you can even supply ac to circuit.
Could you please help me how to add few more components into it and how can I get multiple outputs from it from different points. For eg 5v 3v etc
A voltage regulator circuit is a great way to ensure a steady flow of power to your project. However, if you're using an AC adapter to power your project, you'll need to use a bridge rectifier to protect your regulator from polarity reversal. Without a bridge rectifier, your regulator may be damaged if the polarity of the input voltage changes.
@@SFORSANDEEP you need a 2510 bridge rectifier at the input side and a variable resistor or potentiometer at the output side

Oh no, we have a problem on drc! I know, let's relax the rules. *Runs drc* - no errors! Problem solved 😎
Take note that the capacitors have values based on the expected loads/ power deraws of the circuit, also make sure the diodes use have a smaller break voltage then the voltage source u are using

A 7805 in a PCB without space for a heatsink it's pretty useless
i am a beginner..
i want to know whether what you said means that he did it the wrong way and shouldnt have used that ic without heatsink?
Nope. Heat sink not needed for small currents and lower input voltages.

Depends if you did any online searches on the device(s) you are signed into UA-cam with...cookies and search history give a lot of weight to what is advertised to you depending on your ad choices preferences and UA-cam ad preferences.

Charging a phone this way is disgustingly inefficient. You need to mention that a buck converter would have worked much better for this application.
You give perfect knowledge as compared to colleges give .Thank you so much for making this video and make more videos like this👍🏻
I have never seen a flawless video, today made me do 🎉
Nowadays, linear voltage regulator becoming obsolete, switch mode is present and future
Loved the video, but this should be titled "how to use a voltage regulator". This did nothing to explain how a voltage regulator functions and operates, mostly "it does this and here's how to use it" which is still valuable but a misleading title.
Yeah buddy i totally agree with you i thought he is gonna design a new one and build a prototype then test it and show us. This is also a great video apart from misleading title
Yeah, I thought he was gonna describe the internals of the IC, not how to connect an IC
I LOVE THIS CHANNEL TY FOR YOUR EXISTENCE
Great tutorial! Thank you
I wanted to point out a few things wrong with this PCB. First off, those traces will not stand the current without a significant temperature rise. Unless you meant for the traces to act like fuses then I would increase the width. Next, the diode you use for reverse polarity protection doesn't have much better vf at the currents you were using. While you did (at least I think) purposely choose a diode with low leakage current the vf is the thing you want to focus on in this circuit and the diode doesn't have that great of a vf. And, why not just use a p-channel MOSFET for reverse polarity protection? Furthermore, having the capacitors right next to the regulator probably isn't good for them. If you can even reach current levels that generate a substantial amount of heat without the traces burning out. Please make a new video that teaches people good design ideas and not just use autorouter.
See my new MOSFET explained video here➡️: ua-cam.com/video/AwRJsze_9m4/v-deo.html
I don't think putting a 7805 on a circuit board can really be called "designing a voltage regulator". You bought a voltage regulator and put some filter caps on it.... poorly chosen ones, badly laid out, and with no heatsink, which means you get maybe a third of the current that the 7805 can support. This is a bit like going out and buying a motherboard and CPU, putting them into a box, and claiming you've "designed" a computer.
Oh, nooo... I was looking for such a channel for long. After watching the video I immediately subscribed. Please keep all your videos as simple as possible.
