Pololu 9V, 2.3A Step-Down Voltage Regulator D24V22F9 Temp/Humidity Sensor The higher gear ratio versionThis small synchronous switching step down (or buck) regulator takes an input voltage of up to 36 V and efficiently reduces it to 9 V. The board measures only 0. 7 0. 7 yet delivers typical continuous output currents between 1. 5 A and 2. 3 A, depending on the input voltage, which makes this regulator well suited for powering moderate loads like sensors or small motors. An optional enable input can be used to put the regulator in a low power state
