1 IN Input Voltage. 2 GND Ground. 3 IS Current Sense: IS must be tied to VIN pin if the current limit feature is not used. 4 GATE Gate drive of the external P-Channel MOSFET. 5 EN Enable Input: Logic Level ON/OFF control. Logic high = ON; logic low = OFF. ADJ Adjustable Regulator Feedback Input: Connect to resistor voltage divider. 6 OUT Output Voltage: Connect to drain of P-Channel MOSFET to regulate output to proper voltage. June 2006 2 M9999-062706
