Pololu 1.8V, 500mA Step-Down Voltage Regulator D24V5F1

The compact (0.4" × 0.5") D24V5F1 synchronous buck voltage regulator takes input voltages between 3 V and 36 V and efficiently reduces them to 1.8 V while allowing for a maximum output current of 500 mA. This regulator offers typical efficiencies between 75% and 90%. The pins have a 0.1" spacing, making this board compatible with standard solderless breadboards and perfboards.
