AS2431

SEMICONDUCTOR

Precision Adjustable Shunt Reference

Features

Description

•

Temperature-compensated: 15 ppm/°C

The AS2431 is a three-terminal adjustable shunt regulator providing a

highly accurate bandgap reference. The adjustable shunt regulator is

ideal for a wide variety of linear applications that can be implemented

using external components to obtain adjustable currents and voltages.

Trimmed bandgap reference

Internal amplifier with 100 mA capability

Multiple temperature ranges

In the standard shunt configuration, the combination of low temperature

coefficient (TC), sharp turn-on characteristics, low output impedance

and programmable output voltage make this precision reference an

excellent error amplifier.

Low frequency dynamic output

impedance: < 450 mΩ

•

Low output noise

The AS2431 is a direct replacement for the AS431 in low voltage, low

current applications. It is also available in the very small footprint SOT-

23.
