The S9V11MA switching step-up/step-down regulator efficiently produces a finely adjustable output between 2.5 V and 9 V whether it is higher or lower than the input voltage, which can range from 2 V to 16 V. (Note: minimum start-up voltage is 3 V, but it operates to 2 V after that.) The compact (0.5″ × 0.6″) module can supply a typical output current of up to 1.5 A when the input voltage is close to the output voltage.

Dimensions

Size: 0.5″ × 0.6″ × 0.25″1
Weight: 0.8 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
Maximum quiescent current: 1 mA5

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.
