This input connects to the system main power source, typically 5.0 V.
No connection. These pins are not internally connected.
This input connects to the system auxiliary power source, typically 3.3 V.
This is the regulator and control circuit power ground.
The sense input connects directly to the load allowing precise regulation.
This output is precisely regulated at 3.3 V and is capable of up to 200 mA.
This output is designed to drive the gate of an external P−channel MOSFET switch.
