Step-Down Voltage Regulator D24V3ALV Pololu 2101

The compact (0.4″ × 0.6″) D24V3ALV switching step-down (or buck) voltage regulator takes an input voltage between 4.5 V and 42 V and efficiently reduces it to a lower, user-adjustable voltage. It has a output voltage range of 2.5 V to 7.5 V and a maximum output current of 300mA. The pins have a 0.1″ spacing, making this board compatible with standard solderless breadboards and perfboards.

Specifications

• input voltage: 4.5 V to 42 V (note: the input voltage should be at least a few volts above the output voltage)
