AQ432
1.24V Shunt Ref/Amplifier
TO-92, SOT23, SC70 Package
Product Specification Revision 2007
General Description
AQ432 voltage reference/ amplifier suited control loop voltage power supplies. Functionally similar ubiquitous TL431, AQ432 lower 1.24V reference much wider range operating currents. Particular care taken design minimize overshoot startup allow wide bandwidth. Unlike other 1.24V reference/amplifiers, AQ432 designed stable under conditions does suffer from common overshoot issued associated with other parts voltage parts
Applications
Power supply control loop voltage reference Power management applications Direct replacement AP432, AS432, SPX432, TLV431, LMV431
Features
voltage reference: 1.24V operation voltage reference Improved performance compared 1.24V part types Offered ultra small SC70 package RoHS compliant
Configuration
