EN

Enable Input. Drive EN high to turn on the regulator; drive it low to turn off the regulator. For automatic startup, connect EN to IN.

2

2

GND

Ground.

3, 4

3, 4

IN

Regulator Input Supply. Bypass IN to GND with a 4.7 µF or greater capacitor.

5, 6

5, 6

OUT

Regulated Output Voltage. Bypass OUT to GND with a 4.7 µF or greater capacitor.

7

7

SENSE

Sense. Measures the actual output voltage at the load and feeds it to the error amplifier. Connect SENSE as close as possible to the

load to minimize the effect of IR drop between the regulator output and the load.

8

8

SS

Soft Start. A capacitor connected to this pin determines the soft start time.

0

EP

Exposed Pad. The exposed pad enhances thermal performance and is electrically connected to GND inside the package. It is

recommended to connect the exposed pad to the ground plane on the board.
