AZ431AZ-ATRE1

AZ431-A ADJUSTABLE PRECISION SHUNT REGULATORS Description Pin Assignments The AZ431-A 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. (Top View) ANODE 3 The output voltage of AZ431-A can be set to any value between VREF (2.5V) and the corresponding maximum cathode voltage (36V). 1 The AZ431-A precision reference is offered in two voltage tolerance: 0.4% and 0.8%.
