DESCRIPTION

NAME

NO.

CC

6

—

Connect a capacitor between CC pin and ground to reduce the output noise. The optimum

value for CC is 33 nF.

FAULT

8

Output

FAULT pin goes low during out of regulation conditions like current limit and thermal

shutdown, or when it approaches dropout. Requires a pullup resistor because it is an active-

low, open-drain output.

GND

3

Ground

Ground

IN

2

Input

This is the input supply voltage to the regulator.

OUT

Output

Regulated output voltage

SET

5

Input

In the adjustable version a resistor divider connected to this pin sets the output voltage. The

SET pin is internally disconnected for the fixed versions.

SHDN

7

Input

The SHDN pin allows the part to be turned to an ON or OFF state by pulling SHDN pin high

or low.

DAP

√

—

WSON Only - The DAP (Die Attached Pad) is an exposed pad that does not have an internal

connection; it functions as a thermal relief when soldered to a copper plane. It is recommend

that the DAP be connected to GND. See WSON Mounting section for more information.
