AS2431CBLPB Overview

Precision Adjustable Shunt Reference

SEMICONDUCTOR
AS2431
Reference
Precision Adjustable Shunt
Description
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.
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.
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.
