The KA431A and KA431L are three−terminal adjustable regulators
with a guaranteed thermal stability over the operating temperature
range. The output voltage can be set to any value between VREF
(approximately 2.5 V) and 36 V with two external resistors. These
devices have a typical dynamic output impedance of 0.2 . Active
output circuitry provides a sharp turn−on characteristic, making these
devices excellent replacements for Zener diodes in many applications.
Features
• Programmable Output Voltage to 36 V
• Low Dynamic Output Impedance: 0.2 (Typical)
• Sink Current Capability: 1.0 to 100 mA
• Equivalent Full−Range Temperature Coefficient of 50 ppm/°C
(Typical)
• Temperature Compensated for Operation Over Full Rated
Operating Temperature Range
• Low Output Noise Voltage
• Fast Turn−on Response
