ADJUSTABLE PRECISION SHUNT REGULATORS

AZ431-A

Description

Parametric Table

The AZ431-A series ICs are three-terminal adjustable

shunt regulators with guaranteed thermal stability over a

full operation range. These ICs feature sharp turn-on char-

acteristics, low temperature coefficient and low output

impedance, which make them ideal substitutes for Zener

diodes in applications such as switching power supply,

charger and other adjustable regulators.
