ADJUSTABLE PRECISION SHUNT REGULATORS

AS431

General Description

Features

The AS431 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

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: 0.15Ω Typical

Sink Current Capacity from 1mA to 100 mA

Low Output Noise

The output voltage of these ICs can be set to any value

between V

(2.5V) and the maximum cathode volt-

REF

age (36V).

Wide Operating Range of -40 to 125 C

The AS431 precision reference is offered in two band-

gap tolerance: 0.4% and 0.8%.

Applications

These ICs are available in 4 Packages: TO-92, SOT-23-

3, SOT-23-5 and SOT-89 .
