AS431

ADJUSTABLE PRECISION SHUNT REGULATORS

Description

Pin Assignments

The AS431 is a three-terminal adjustable shunt regulator with

guaranteed thermal stability over a full operation range. It features

sharp turn-on characteristics, low temperature coefficient and low

output impedance, which make it ideal substitute for Zener diode in

applications such as switching power supply, charger and other

adjustable regulators.
