PIN FUNCTION DESCRIPTION

Pin No.

Pin Name

Description

1

EN

Enable pin. Driving EN over 0.9 V turns on the regulator. Driving EN below 0.4 V puts the regulator

into shutdown mode.

2

GND

Power supply ground.

3

N/C

Not connected. This pin can be tied to ground to improve thermal dissipation.

4

OUT

Regulated output voltage. A minimum 4.7

mF ceramic capacitor is needed from this pin to ground to

assure stability.

5

OUT_S

Output voltage sense connection. This pin should be connected to the output voltage rail.

6

IN

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

−

Exposed

Pad

This pad enhances thermal performance and is electrically connected to GND. It is recommended

that the exposed pad is connected to the ground plane on the board or otherwise left open.
