AAT AAT1204
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. This is a intelligent power z Output Short Circuit Protection source selection device with a low-dropout regulator for either VCC50 or VSB50 inputs, and Pin Configuration a low-resistance bypass switch for the AUX33 input. The device has an incorporated reverse-blocking VSB50 GND 8 1 scheme to prevent excess leakage from the input GND 2 7 VCC50 terminals in the event that the output voltage is OUT33 GND 3 6 greater than the input voltage.
