Pin No. Mnemonic Description
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.
