AZ9431BQ
AUTOMOTIVE COMPLIANT 1.24V ADJUSTABLE PRECISION SHUNT REGULATOR
Description
The AZ9431BQ 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 AZ9431BQ precision reference is offered in 1.0% voltage
tolerance.
The
AZ9431BQ are available SOT23 that are qualified to AEC Q100
standards for high reliability and are PPAP capable.
