The 4-25V Adjustable Step-Down Regulator with Converter by Pololu is a compact, low-power voltage regulator capable of providing up to 600mA of current. It features an adjustable output voltage with a range of 4V to 25V, and an input voltage ranging from 4V to 50V. The regulator measures 13 x 10mm in size. The regulator features an internal switchmode step-down converter that efficiently steps down the input voltage to the desired output voltage with minimal heat generation. It is ideal for powering project and application needs such as microcontrollers, LCDs, LEDs, amplifiers, motors, and other similar applications.
