AZ431BZ-ATRE1

Description
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%.
