LOW VOLTAGE (1.24V) ADJUSTABLE PRECISION SHUNT REGULATOR

AZ431L

General Description

Features

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.

Wide Programmable Precise Output Voltage from

1.24V to 18V

High Stability under Capacitive Load

Low Temperature Deviation: 3mV Typical

Low Equivalent Full-range Temperature Coeffi-

cient: 20PPM/ C Typical

Low Dynamic Output Resistance: 0.05Ω Typical

High Sink Current Capacity from 0.1mA to

100mA

The output voltage can be set to any value between

1.24V and 18V with two external resistors.

Low Output Noise

Wide Operating Range of -40 to 125 C

The AZ431L precision reference is offered in two volt-

age tolerance: 0.5% and 1.0%.

Applications

These ICs are available in 4 packages: TO-92 (bulk or

ammo packing), SOT-23, SOT-23-5, SOT-89-3.
