Pin Descriptions

Pin Number

Pin Name

Function

A1

VIN

Input Voltage

B1

SS

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

open for a typical 340

μs startup 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

B2

SENSE/ADJ

Sense Input (SENSE). Connect to load.

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

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

C2

GND

Ground
