PIN DESCRIPTION

PACKAGE

PIN NO.

PIN NAME

DESCRIPTION

SOT-25

1

Input for voltage input. A 1µF or greater capacitor should be placed in

this pin.

2

GND

Ground.

3

EN

Enable pin. Pulling his pin low, can shut down the PMOS pass transistor,

and the current consuming can be set less than 1µA.

4

NC

5

Output voltage pin. The capacitor which connected between this pin and

GND should be decoupled with a 2.2µF or a greater value low ESR

ceramic capacitor.

SOT-26

1

SENSE

Remote Sense.

2

GND

Ground.

3

BYP

Bypass capacitor for noise reduction.

4

EN

Enable Input.

5

Supply Input.

6

Output Voltage.
