The Pololu S8V3A voltage regulator is a switching regulator or switched-mode power supply (SMPS) or DC-to-DC converter with a single-ended primary-inductor converter (SEPIC) topology. It takes an input voltage between 1.5 V to 12 V that can be increased or decreased with a screwdriver by turning the potentiometer. The output voltage produces ranges between 2V and 12V and can be verified using a multimeter. The output current is 300mA. This device is well-suited for battery-powered applications in which the output voltage is decreasing while battery is discharging.
The S8V3A regulator has a shutdown feature that can also be used as an under-voltage protection mechanism for batteries that respond poorly to being over-discharged. The shutdown threshold can be set with one external resistor; please see the Shutdown section below for details.
The regulator has under-voltage protection, and thermal shutdown prevents damage from overheating; the board does not have reverse-voltage protection. For applications where the output is significantly different from the input, a regulator optimized for boosting (stepping up) or bucking (stepping down) is more efficient, but for small applications where efficiency is not a top priority, this board can be a convenient.
