Datasheet Diodes AZ9431Q

AZ9431Q
AUTOMOTIVE COMPLIANT 1.24V ADJUSTABLE PRECISION SHUNT REGULATOR Description Pin Assignments
SOT23 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. REF 1
3 CATHODE The output voltage can be set to any value between 1.24V and 18V
with two external resistors. ANODE 2 (Top View) 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. Typical Applications Circuit
