VIN

Unregulated Input Supply. Bypass with a capacitor to GND.

GND

Ground pin.

EN

Chip enable, pull high to enable the regulator.

ADJ

Adjustable feedback voltage. The output voltage is set by the external pair of

resistors R1 and R2 and the output voltage is calculated by :

VOUT = 1.235 * (1 + R1/R2) Volts

VOUT

Regulated Output Voltage. Bypass with a capacitor to GND.
