PIN FUNCTION DESCRIPTION

Pin No.

Pin Name

Description

1

OUT

Regulated output voltage pin. A small ceramic capacitor with minimum value of 1

mF is needed from this

pin to ground to assure stability.

2

GND

Power supply ground.

3

EN

Driving EN over 0.9 V turns on the regulator. Driving EN below 0.4 V puts the regulator into shutdown

mode.

4

IN

Input pin. A small capacitor is needed from this pin to ground to assure stability.

−

EPAD

Exposed pad should be connected directly to the GND pin. Soldered to a large ground copper plane allows

for effective heat removal.
