Pololu 5V Step-Up/小玩具嵌入式视频观看 Voltage Regulator S7V8F5

The S7V8F5 switching step-up/小玩具嵌入式视频观看 regulator efficiently produces a fixed 5 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.
