Data Sheet
LOW VOLTAGE (1.24V) ADJUSTABLE PRECISION SHUNT REGULATOR
AZ431L
General Description
The AZ431L series ICs are low voltage three-terminal
adjustable 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 applications such as
switching power supply, charger, motherboard and
other adjustable regulators.
The output voltage can be set to any value between
1.24V and 18V with two external resistors.
The AZ431L precision reference is offered in two volt-
age tolerance: 0.5% and 1.0%.
These ICs are available in 4 packages: TO-92 (bulk or
ammo packing), SOT-23, SOT-23-5 and SOT-89.
