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.
