12V, 100mA Step-Down Voltage Regulator D45V1E1F12

The **Pololu 12V, 100mA Step-Down Voltage Regulator D45V1E1F12** is an ultra-compact buck converter that provides a fixed 12V output from input voltages ranging between 13.5V and 45V. It delivers up to 100?mA of continuous current, making it ideal for powering low-power 12V devices such as sensors, control circuitry, or signal interfaces. Despite its small size, the regulator integrates key protection features including over-current limiting, thermal shutdown, and under-voltage lockout. Its efficient operation, wide input range, and minimal footprint make it an excellent solution for compact systems that need a reliable 12V supply in space-constrained environments.
