NAME

FUNCTION

1

2

GND

Ground pin of the circuitry. All voltage levels are measured with respect to this pin.

3

FB

Voltage Feedback Pin. Connecting this pin to an external resistor divider receives the feedback voltage

of the regulator.

4

POK

Power-OK signal output pin. This pin is an open-drain output used to indicate the status of output

voltage by sensing FB voltage. This pin is pulled low when output voltage is not within the Power-OK

voltage window.

5

DRV

This pin drives the gate of an external N-channel MOSFET for linear regulator.

6

VCC

Power input pin of the device. The voltage at this pin is monitored for Power-On-Reset purpose.
