M Description

The IR9431/IR9431N is a shunt regulator IC -

which adjusts output voltages from 2.5 to 36V

through external resistors over the entire operating

temperature range. It has a typical dynamic output

impedances of 0.2Q. Active output circuitry pro-

vides a very sharp turn-on characteristics making it .

excellent replacemens for zener diodes in many ap-

plications.
