Description
1
Source
This is the source of the power FET and connects to the PMIC pin of the same name.
2
Gate
This pin is the gate of the FET switch.
3, 7
Vin
Positive input voltage to the device.
4
Ground
Negative input voltage to the device. This is used as the internal reference for the IC.
5
Vout
This is the output of the internal LDO. It passes the input voltage through to the output and clamps
that voltage if it exceeds the regulation limit.
6, 8
Drain
Positive input voltage to the device.

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
