AQ431R

2.5V Shunt Ref/Amplifier

TO-92 and SOT23 Package

Preliminary Specification

Revision 1.6

June 15, 2007

General Description

Applications

The AQ431R is a three-terminal adjustable

shunt regulator based on a highly stable

bandgap reference and is an excellent

replacement for standard TL431 references

when used as a secondary feedback element

in Switch Mode Power Supplies.

• Power supply control loop

• Low TC voltage reference

• Power management applications

Features

• Programmable precise output voltage

The AQ431R meets all of the requirements of

the standard 431 specifications that are

needed to monitor the secondary output

voltage and provide the feedback signal to

the primary through an opto-coupler. It is

offered in both the very popular SOT23-3 and

TO-92 packages.

2.5V to 15V

• Wide temp range: -40º to 85ºC standard

• Improved stability with capacitive loads

• Low TC voltage reference

• Wide range of package options

• RoHS compliant
