The S7V8F3 switching step-up/step-down regulator efficiently produces a fixed 3.3 V output from input voltages between 2.7 V and 11.8 V. Its ability to convert both higher and lower input voltages makes it useful for applications where the power supply voltage can vary greatly, as with batteries that start above but discharge below the regulated voltage. The compact (0.45″ × 0.65″) module has a typical efficiency of over 90% and can deliver 500 mA to 1 A across most of the input voltage range.

Notes:
- 1
- Without included optional headers.
- 2
- When stepping down; current available when stepping up depends on input and output voltages (over 500 mA in most configurations).
- 3
- While enabled (SHDN = HIGH) with no load. Actual quiescent current depends on input voltage.
