Description

A1

VIN

Regulator Input Supply. Bypass VIN to GND with a 2.2 μF or greater capacitor.

B1

SS

Soft Start. An external capacitor connected to this pin determines the soft start time. Leave this pin open

for a typical 380 μs start-up time. Do not ground this pin.

C1

EN

The enable pin controls the operation of the LDO. Drive EN high to turn on the regulator. Drive EN low

to turn off the regulator. For automatic startup, connect EN to VIN.

A2

VOUT

Regulated Output Voltage. Bypass VOUT to GND with a 2.2 μF or greater capacitor.

B2

SENSE/ADJ

Sense Input (SENSE). Connect to load.

Adjustable Model (ADJ). The adjustable model has a fixed output set to 1.2 V. The output can be set to a

voltage higher than 1.2 V by connecting an external resistor divider to the ADJ pin.

C2

GND

Ground.
