PIN FUNCTION DESCRIPTION

TSOP−5

Pin No.

QFN 2x2

Pin No.

Pin Name

Description

Vin

Positive power supply input voltage.

2, 5

GND

Power supply ground.

Enable

This input is used to place the device into low−power standby. When this input is pulled to a logic

low, the device is disabled. If this function is not used, Enable should be connected to Vin.

N/C

No internal connection.

Vout

Regulated output voltage.
