ADJUSTABLE PRECISION SHUNT REGULATORS

AZ431-B

General Description

Features

The AZ431-B is a three-terminal adjustable shunt regu-

lator with guaranteed thermal stability over a full oper-

ation range. It features sharp turn-on characteristics,

low temperature coefficient and low output impedance,

which make it ideal substitute for Zener diode in appli-

cations such as switching power supply, charger and

other adjustable regulators.

Programmable Precise Output Voltage from 2.5V

to 18V

High Stability under Capacitive Load

Low Temperature Deviation: 4.5mV Typical

Low Equivalent Full-range Temperature Coeffi-

cient with 20PPM/ C Typical

Sink Current Capacity from 1mA to 100mA

Low Output Noise

The output voltage of AZ431-B can be set to any value

between V

(2.5V) and the corresponding maximum

Wide Operating Range of -40 to 125 C

REF

cathode voltage.

Applications

The AZ431-B precision reference is offered in two

voltage tolerance: 0.4% and 0.8%.
