3.3V, 100mA Step-Down Voltage Regulator D45V1E2F3

The **Pololu 3.3V, 100mA Step-Down Voltage Regulator D45V1E2F3** is a compact and efficient switching regulator designed to provide a fixed 3.3V output from input voltages between 4.5V and 45V. Capable of supplying up to 100?mA of continuous current, it is ideal for low-power electronics such as sensors, microcontrollers, and wireless modules. This regulator features a very small footprint, making it well-suited for space-constrained applications, and includes essential protections like over-current limiting, thermal shutdown, and under-voltage lockout. Its ultra-low quiescent current and wide input range make it a reliable power solution for energy-efficient embedded systems.
