Pololu 3.3V, 1A Step-Down Voltage Regulator D24V10F3


8 in stock

The compact (0.5″ × 0.7″) D24V10F3 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 1 A. 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.

1 Without included optional headers.
2 For small loads; this voltage rises approximately linearly up to 4.1 V at 1 A output.
3 While enabled (SHDN = HIGH) with no load; while disabled it is proportional to the input voltage   (360 μA when the input is 36 V).
