PIN NAME

DESCRIPTION

SHDN

Active-Low Shutdown Input. A logic low at SHDN reduces supply current to

0.01µA. In shutdown, the POK output is low. Connect SHDN to VIN for normal

operation.

VIN

Power Input Voltage. Supply voltage can range from 2.25V to 6V. Bypass with a

68µF capacitor to GND.

VOUT

Output Voltage

ADJ

Voltage-adjust Input. Connect ADJ to GND for preset output. Connect an external

resistive voltage-divider from VOUT to ADJ to set the output voltage between 0.8V

and 6V. The ADJ regulation voltage is 800mV

Soft start time setting. For adjustable soft start time version, connect a capacitor

from SS to gnd to set the soft start time.

GND

Ground
