PIN NAME

DESCRIPTION

SOP-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 1µF or a greater value

low ESR ceramic capacitor.

SOP-26

1

SENSE

Remote Sense.
