Pin Name
Pin Function
VIN
Unregulated Input Supply. Bypass with a capacitor to GND.
GND
Ground pin.
EN
Chip enable, pull high to enable the regulator.
Adjustable feedback voltage. The output voltage is set by the external pair of
ADJ
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.
