  1. Pololu 5V, 500mA Step-Down Voltage Regulator D24V5F5 POLOLU-2843 Pololu Australia - Express Delivery Australia Wide

    Pololu 5V, 500mA Step-Down Voltage Regulator D24V5F5

    SKU: POLOLU-2843
    The compact (0.4″ × 0.5″) D24V5F5 synchronous buck voltage regulator takes an input voltage of up to 36 V and efficiently reduces it to 5 V while allowing for a maximum output current of 500 mA. This regulator offers typical efficiencies between 85% and 90% and has a very low dropout, so it can be used with input voltages as low as a few hundred millivolts above 5 V. The pins have a 0.1″ spacing, making this board compatible with standard solderless breadboards and perfboards. Learn More

  2. Pololu 5V, 2.5A Step-Down Voltage Regulator D24V25F5 POLOLU-2850 Pololu Australia - Express Delivery Australia Wide

    Pololu 5V, 2.5A Step-Down Voltage Regulator D24V25F5

    SKU: POLOLU-2850
    This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 5 V. The board measures only 0.7″ × 0.7″, but it allows a typical continuous output current of up to 2.5 A. Typical efficiencies of 85% to 95% make this regulator well suited for powering moderate loads like sensors or small motors. High efficiencies are maintained at light loads by dynamically changing the switching frequency, and an optional shutdown pin enables a low-power state with a current draw of a few hundred microamps.
