Pin Function DescriptionsPin No.FixedAdjustableMnemonicDescription 1 N/A GND This pin is internally connected to ground. N/A 1 ADJ Adjust. A resistor divider from OUT to ADJ sets the output voltage. 2 2 IN Regulator Input Supply. Bypass IN to GND with a 1 µF or greater capacitor. 3 3 OUT Regulated Output Voltage. Bypass OUT to GND with a 1 µF or greater capacitor. 4 4 EN Enable Input. Drive EN high to turn on the regulator; drive it low to turn off the regulator. For automatic startup, connect EN to IN. 5 5 GND Ground. 6 6 GND Ground. 7 7 GND Ground. 8 8 GND Ground. Rev.
