ADJUSTABLE PRECISION SHUNT REGULATORS

AZ431

General Description

Features

The AZ431 series ICs 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 applications such as switching

power supply, charger and other adjustable regulators.

Programmable Precise Output Voltage from 2.5V

to 36V or 18V

Very Accurate Reference Voltage: 0.15% Typical

High Stability under Capacitive Load

Low Temperature Deviation: 4.5mV Typical

Low Equivalent Full-range Temperature Coeffi-

cient with 20PPM/ C Typical

Low Dynamic Output Resistance: 0.2Ω Typical

Sink Current Capacity from 1mA to 100 mA

Low Output Noise

The AZ431 series ICs contain two voltage types,

AZ431-A for 40V and AZ431-B for 20V. The output

voltage of both types can be set to any value between

(2.5V) and the corresponding maximum cathode

REF

Wide Operating Range of -40 to 125 C

voltage.

Applications

The AZ431 precision reference is offered in two band-

gap tolerance: 0.4% and 0.8%.
