2.5-9V Fine-Adjust Step-Up/Step-Down Voltage Regulator S9V11MA

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.

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.
