If you put vias under the back (ground) of the back of the AMS1117 to the back of the PCB and make a large ground plane on back of the PCB will help wick the heat away Remember voltage regulators have to dissipate heat when they regulate voltage down...so you need a heatsink on the chip...or a heatsink of copper on the PCB
So it's not possible to step down 5V to 3.3V on the Arduino itself? I just want to build a device that will make a button do the opposite. Like splice a wire, install a button and have it do a digital write to LOW when it's pressed, and HIGH when it's not pressed. Thankfully it's a 3.3v line so maybe I could just power the Arduino with the existing line, then just do digital write from there.
This is the best test I could offer. You should come to conclusion from the test result as there would be 100s of way to test and all could not be done in short video.
I have explained it. But when you buy it on eBay and AliExpress people put incorrect value in the title of the item so I am showing them that those values are incorrect.
the forward bias voltage of diode is about 0.7V so to get 2V drop, you will need to put 3 of them an still it will not be exact it would be 2.1V drop. The voltage drop on diode is wasting energy as the current passes. not a good idea.
@@robojax I want to know whether Transformer phasing out as most of the people are using AC-DC adapter, LM7805 and LM2596 types converter and why? Must reply!
Robojax these types of regulators are not good. The bigger the difference in input to output, the more heat it will generate. Look at the buck regulators, they are better and more efficient
On page 3 of datasheet www.advanced-monolithic.com/pdf/ds1117.pdf it shown the Quiescent Current Typicaly 5ma and Maximum 11mA , Please subscribe. I appreciate it and helps my channel grow. Thank you
![How to replace a 5V Regulator (AMS1117) on an Arduino Uno - [Ep. 0001]](http://i.ytimg.com/vi/NzlzX89vJXQ/mqdefault.jpg)
Some people read datasheet before inserting two fingers into an outlet. It is 800mA IOut, not 1Amp !!!
it may be 1amp on sporadic burts , not continually ...

thanks for this video, I have doubts about that circuit, but look promising, I buy several ones
Glad I could help
Yes, excellent testing. Very helpful. Thank you.
Glad it was helpful!

Arduino has 3.3v output when you power it via USB
Sir, how about efficiency at @100-200mA ?
esp07 max input is 500ma is AMS1117 suitable as its output is 1Amp
Hi, I believe I have shown the datasheet, mentioned the maximum current and tested it.
Can you tell me approximately, what the power consumption of it is?
I have tested all provided all the results. it is the efficiency. I have shown that.
Excellent testing.....thank you!
You are welcome.
what do you use for load testing?
It is called 150W Electronic Load sold on eBay. I have a video on that ua-cam.com/video/-kI7OtTHd18/v-deo.html
Nice video, thanks :)
does it work perfectly if i take output load of 600mA ? i mean for a longer period?
This is the best test I could offer. You should come to conclusion from the test result as there would be 100s of way to test and all could not be done in short video.
Not for longer period
Thats the reason why i mount heat sinks on theese devices 😅
very good idea to add heat sink.
If my power supply amps are higher than 1amp does it still produce 1 amp out?
Yes. Higher power at input never would be just excess and will not be used.
Read the specs... it has a max of 700ma.... why would you try over. It will just fail.
I have explained it. But when you buy it on eBay and AliExpress people put incorrect value in the title of the item so I am showing them that those values are incorrect.
What if connected forward biased diode to drop 5 v to 3v
the forward bias voltage of diode is about 0.7V so to get 2V drop, you will need to put 3 of them an still it will not be exact it would be 2.1V drop. The voltage drop on diode is wasting energy as the current passes. not a good idea.
Ok tq
What if 3.3v zener diode used
Is it better than LM7805?
7805 is getting up to 15V and converting 5V output. This module can only get 5V and output 3.3V. They are two different things.

Max power disipation is 1.2w
Can you give me file PDF AMS1117 ?
here is the datasheet www.advanced-monolithic.com/pdf/ds1117.pdf
how much current does ams1117 ic consumes??

cool video!!
Thank you.
