Pololu 3.3V Step-Up/Step-Down Voltage Regulator S7V8F3 updated 12-22 Soldering iron and solder isThe 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
