Description

ADP170

ADP171

1

VIN

Regulator Input Supply. Bypass VIN to GND with a 1 μF or greater capacitor.

2

GND

Ground.

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

VOUT

Regulated Output Voltage. Bypass VOUT to GND with a 1 μF or greater capacitor.
