Description

1

EN

Enable pin. It controls the electrical on/off of the device. When connected to logic

low, the device shuts off and consumes less than 1µA of current. Logic high will

resume normal operation.

PG

Power Good pin. It is an open collector, active high output that indicates the

threshold, the PG pin goes in to a high impedance state. When the device is out

of regulation or shutdown, the PG pin is pulled low. A 10KΩ to 1MΩ resistor

2

Input supply Voltage. It powers the internal control circuitry and the internal power

3

GND

Ground connection.

4

Output Voltage

5

ADJ

Provides feedback to error amplifier from the resistive divider that sets the output

voltage.
