Pololu 12V, 500mA Step-Down Voltage Regulator D24V5F12

Pololu 12V, 500mA Step-Down Voltage Regulator D24V5F12

$ 1.45 $ 5.95
The compact (0.4″ × 0.5″) D24V5F12 synchronous buck voltage regulator takes an input voltage of up to 36 V and efficiently reduces it to 12 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 12 V. The pins have a 0.1″ spacing, making this board compatible with standard solderless breadboards and perfboards.

Notes:

1
Without included optional headers.
2
For small loads; this voltage rises approximately linearly up to 12.9 V at 500 mA output.
