Pololu Adjustable Step-Up/Step-Down Voltage Regulator S7V8A Shipping:1 day but it does not directlyThe S7V8A switching step up step down regulator efficiently produces an adjustable output between 2. 5 V to 8 V 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
