BCD AZ431AK-ATR Adjustable precision shunt regulator Datasheet

Product Brief
ADJUSTABLE PRECISION SHUNT REGULATORS
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 characteristics, 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.
The AZ431-A series ICs are of 40V voltage type. Its output voltage can be set to any value between VREF(2.5V)
and 36V.
The AZ431-A precision reference is offered in two bandgap tolerance: 0.4% and 0.8%.
