| AQ431L 1.24V Shunt Ref/Amplifier TO-92, SOT23, SC70 Package Product Specification Revision 1.5 November 15, 2005 General Description The AQ431L is a low voltage reference/ amplifier suited for the control loop of low voltage power supplies. Functionally similar to the ubiquitous TL431, the AQ431L has a lower 1.24V reference and a much wider range of operating currents. Particular care was taken in the design to minimize overshoot at startup and to allow wide AC bandwidth. Applications * Power supply control loop * Low TC low voltage reference * Power management applications Features * * * * Low voltage reference: 1.24V 40 uA to 100 mA operation Low TC voltage reference Improved AC, DC performance compared to TLV431, 432 part types * Offered in ultra small SC70 package * RoHS compliant Pin Configuration Pin Descriptions Pin Name CATH REF ANODE Function Output and supply terminal, must be greater than 1.2V for normal operation Input, nominally 1.24V in normal operation.

Absolute Maximum Ratings Stress greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These stress ratings only, and functional operation of the device at these or any conditions beyond those indicated under recommended Operating Conditions is not implied. Exposure to "Absolute Maximum Rating" for extended periods may affect device reliability. Use of standard ESD handling precautions is required.
