Pin Name

Pin Number

Description

IN

1

Unregulated Input Voltage. This pin should be connected to the

positive terminal of the input capacitor. Bypass with 1μF capacitor to

GND. Input voltage can range from 2.6V to 50V.

SHDN

2

Active-High Shutdown Input. A logic high reduces the ground pin

current to < 1μA. Connect this pin to GND for normal operation.

NC

3

Not Connected. This pins must be not connected.

GND

4

Ground.

POK

5

Power-OK Output. Active-low, open-drain output indicates an

out-of-regulation condition. Connect a 100k

Ω pull-up resistor to pin OUT

for logic levels. Leave this pin unconnected if the Power-OK feature is not

used.

NC

6

Not Connected. This pins is not connected.

OUT

7

Regulated Output Voltage. This pin should be connected to the positive

side of the load and to the positive terminal of the output capacitor.

Current flowing out of this pin is equivalent to a DC load current. Fixed

1.2, 1.8, 2.5, 3.0, 3.3, 4.5, 5.0 and 5.5V output, as well as versions from 1.2V

up to 5.5V can be ordered. Bypass with 1μF capacitor to GND.

NC

8

Not Connected. This pin is not connected.

Exposed Pad

9

Exposed Pad. This pin functions as a heat sink. Solder it to a large pad or

to the circuit-board ground plane to maximize power dissipation.
