LOW VOLTAGE (1.25V) ADJUSTABLE PRECISION SHUNT REGULATOR
Description
The AZ432 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 1.25V and 18V
with two external resistors.
The AZ432 precision reference is offered in two voltage 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.
