Pin Description

Pin Number

Pin Name

Pin Function

1

EN

Enable (Input): CMOS compatible input.

Logic high = enable, logic low = shutdown.

2

IN

Input Voltage: Supplies the current to the output power device

3

GND, TAB

Ground: TAB is also connected internally to the IC’s ground on D-PAK.

4

OUT

Regulator Output: The output voltage is set by the resistor divider

connected from OUT to GND (with the divided connection tied to ADJ).

A minimum value capacitor must be used to maintain stability. See

Applications Information.

5

ADJ

Adjustable Regulator Feedback Input: Connect to the resistor voltage

divider that is placed from OUT to GND in order to set the output

voltage.
