Description
General part information
AS431ARTR-G1
The AS431 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. The output voltage of AS431 can be set to any value between VREF (2.5V) and the corresponding maximum cathode voltage (36V). The AS431 precision reference is offered in two voltage tolerance: 0.5% and 1.0%.
