400-mA MULTI-INPUT LOW-DROPOUT REGULATOR WITH VAUX SWITCH
Features z plete Power Management
Description The AAT1204 is a multi-input low-dropout z Automatic Input Voltage Selection regulator that provides constant output supply z Input Voltage Source Detector With 3.3V at the output capable of driving a 400-mA Hysteresis load. z 400-mA Load Current Capability With The AAT1204 provides regulated power output VCC50 or VSB50 or AUX33 Input Source for systems that have multiple input sources and z Integrated Low rDS (on) Switch require constant voltage source with a z Regulated Output 3.3V (fixed) low-dropout voltage. This is a intelligent power z...
