Mnemonic Description ADP170 ADP171
1 1 VIN Regulator Input Supply. Bypass VIN to GND with a 1 μF or greater capacitor.
2 2 GND Ground.
3 3 EN
Enable Input. Drive EN high to turn on the regulator; drive EN low to turn off the regulator. For
automatic startup, connect EN to VIN.
4 NC No Connect. Not connected internally.
4 ADJ Adjust. A resistor divider from VOUT to ADJ sets the output voltage.
5 5 VOUT Regulated Output Voltage. Bypass VOUT to GND with a 1 μF or greater capacitor.
