Pin Function
Input Voltage.
Ground.
Current Sense: IS must be tied to VIN pin if the current limit feature is not used.
Gate drive of the external P-Channel MOSFET.
Enable Input: Logic Level ON/OFF control. Logic high = ON; logic low = OFF.
Adjustable Regulator Feedback Input: Connect to resistor voltage divider.
Output Voltage: Connect to drain of P-Channel MOSFET to regulate output to
proper voltage.
