5V, 3A Step-Up/Step-Down Voltage Regulator S13V30F5

The Pololu 5V, 3A Step-Up/Step-Down Voltage Regulator S13V30F5 is a powerful and compact DC-DC converter that provides a fixed 5V output from input voltages ranging from 2.8V to 22V. Designed around a buck-boost topology, it can seamlessly step voltage up or down to maintain a stable 5V output, making it ideal for systems powered by batteries or varying power sources. This regulator can deliver up to 3A of continuous current under typical conditions and features built-in safety protections including over-current limiting, thermal shutdown, and under-voltage lockout. Its high efficiency and reliable output make it a popular choice for powering microcontrollers, sensors, and other 5V electronics in robotics, embedded systems, and portable devices.
