AZ9431Q

Description

The AZ9431Q series 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 automotive and high-reliability applications requiring an improvement in zener performance. The output voltage can be set to any value between 1.24V and 18V with two external resistors. The AZ9431Q precision reference is offered in 0.5% and 1.0% voltage tolerance. The AZ9431Q are available in SOT23 that are qualified to AEC-Q100 standards for high reliability and are PPAP capable.
