Pololu Buck Regulator, Vin 3.4-36V, Vout 3.3V 0.5A Input

The compact 10 x 12.7mm synchronous buck voltage regulator takes an input voltage of up to 36 V and efficiently reduces it to 3.3 V while allowing for a maximum output current of 500 mA. This regulator offers typical efficiencies between 80% and 90% and has a very low dropout, so it can be used with input voltages as low as a few hundred millivolts above 3.3 V. The pins have a 0.1″ spacing, making this board compatible with standard solderless breadboards and perfboards.

Voltage regulator

The SHDN pin can be driven low (under 0.4 V) to turn off the output and put the board into a low-power state. There is a 100 kΩ pull-up resistor between the SHDN pin and VIN, so if you want to leave the board permanently enabled, the SHDN pin can be left disconnected. While the SHDN pin is being driven low, the current draw of the regulator is dominated by the current through the pull-up resistor and will be proportional to the input voltage. (At 36 V in it will draw about 360 μA.)
