2.5V Shunt Ref/Amplifier
TO-92 and SOT23 Package
Preliminary Specification Revision 1.6 June 15, 2007
General Description
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. 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.
Applications Power supply control loop Low TC voltage reference Power management applications Features Programmable precise output voltage
2.5V to 15V Wide temp range: -40 to 85C standard Improved stability with capacitive loads Low TC voltage reference Wide range of package options RoHS compliant
