9V, 500mA Step-Down Voltage Regulator D24V5F9 Pololu 2845

9V, 500mA Step-Down Voltage Regulator D24V5F9 Pololu 2845

The compact (0.4″ × 0.5″) D24V5F9 synchronous buck voltage regulator takes an input voltage of up to 36 V and efficiently reduces it to 9 V while allowing for a maximum output current of 500 mA. This regulator offers typical efficiencies between 85% and 93% and has a very low dropout, so it can be used with input voltages as low as a few hundred millivolts above 9 V. The pins have a 0.1″ spacing, making this board compatible with standard solderless breadboards and perfboards.
