Pololu, Buck Boost Regulator, Vin 2.7-11.8V, Vout 2.5 - 8V 1A

The 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 can deliver 500 mA to 1 A across most combinations of input and output voltages.

Quick Spec

  • Minimum Operating Voltage: 2.7V
  • Maximum Operating Voltage: 11.8V
  • Maximum Output Current: 1A
  • Minimum Output Voltage: 2.5V
  • Maximum Output Voltage: 8V
  • No Reverse Voltage Protection
  • Maximum Quiescent Current: 0.3mA

Pinouts (back of device)



The step-up/step-down regulator has four connections: shutdown (SHDN), input voltage (VIN), ground (GND), and output voltage (VOUT).

The SHDN pin can be driven low (under 0.4 V) to power down the regulator and put it in a low-power state. The quiescent current in this sleep mode is dominated by the current in the 100k pull-up resistor from SHDN to VIN. With SHDN held low, this resistor will draw 10 µA per volt on VIN (for example, the sleep current with a 5 V input will be 50 µA). The SHDN pin can be driven high (above 1.2 V) to enable the board, or it can be connected to VIN or left disconnected if you want to leave the board permanently enabled
