D45V5FX Step Down Voltage Regulators

Small, fixed‑output step‑down regulators convert a wide input voltage range down to common logic rails such as 3.3 V, 5 V, 6 V, 9 V and 12 V with a typical 500 mA output. Their compact PCB footprint and switching topology deliver higher efficiency than linear parts when running from elevated inputs, while dropout behaviour and thermal dissipation define minimum input/headroom and sustained output.

These modules suit powering microcontrollers, sensors, communication modules, small actuators and LED loads from batteries, vehicle supplies or industrial rails. Key attributes include fixed output voltages, wide input ranges, package size, output current capability, dropout characteristics and thermal/efficiency performance for straightforward integration.
