Step-Down Voltage Regulator D15V70F5S3 Pololu 2111

The compact (1.9"×0.6") D15V70F5S3 switching step-down (or buck) voltage regulator takes an input voltage between 4.5 V and 24 V and efficiently reduces it to a lower, user-selectable voltage. The selectable output voltages are 5 V and 3.3 V, and it can deliver 7 A continuous in typical applications.
