AS431H

ADJUSTABLE PRECISION SHUNT REGULATORS

Description

Pin Assignments

The AS431H 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.

ANODE

The output voltage of AS431H can be set to any value between V_REF

(2.495V) and the corresponding maximum cathode voltage (36V).

The AS431H precision reference is offered in two voltage tolerance:

0.5% and 1.0%.
