Description

The LM431SA/LM431SB/LM431SC are three terminal

output adjustable regulators with thermal stability over

operating temperature range. The output voltage can be set

any value between V

REF

(approximately 2.5 volts) and 36

volts with two external resistors. These devices have a

typical dynamic output impedance of 0.2Ω Active output

circuit provides a sharp turn-on characteristic, making these

devices excellent replacement for Zener Diodes in many

applications.
