Dimensions

Size: 0.5″ × 0.6″ × 0.25″1
Weight: 1.0 g1

General specifications

Minimum operating voltage: 2 V2
Maximum operating voltage: 16 V
Maximum output current: 1.5 A3
Minimum output voltage: 2.5 V4
Maximum output voltage: 9 V4
Reverse voltage protection?: N

Identifying markings

PCB dev codes: reg20b
Other PCB markings: 0J10534

Notes:

1
Without included optional headers.
2
Note: the minimum startup voltage is 3V, but the regulator can operate down to 2V after startup.
3
Under typical conditions, where the input voltage is close to the output voltage. Maximum output current can be higher when stepping down and lower when stepping up.
4
Output voltage is set by a built-in precision 12-turn potentiometer.
5
With no load. Actual quiescent current depends on input voltage; it is typically under 300 µA when the input voltage is close to the output voltage.
