Recom Switching Regulator Through Hole 3.3V DC Output Voltage 32V DC Input 2A Output Current R-78B3.3-2.0

Recom R-78B3.3-2.0 switching regulator is a through-hole mounted voltage converter designed for industrial, electronic component, and power management applications. It converts input voltages between 4.75V and 32V DC into a stable 3.3V DC output at 2 amps, ensuring compatibility with a wide range of electronic devices and circuits.

The regulator is housed in a compact SIP-3 package measuring 11.5mm by 8.5mm by 8.5mm, making it ideal for space-constrained circuit boards. Featuring high efficiency of up to 92%, it minimizes energy loss and heat dissipation, eliminating the need for bulky heat sinks. The device provides fast startup times of 10 milliseconds, suitable for systems requiring rapid power availability.

Robust protection features include built-in overtemperature shutdown and continuous short-circuit protection, enhancing system reliability in demanding environments. It operates reliably over a wide temperature range from -40°C to +70°C. With low ripple and noise of 50mV peak-to-peak and strict line and load regulation (±0.5% and ±1%, respectively), it ensures clean and stable power delivery.

Pin-compatible with common TO220 linear regulators, this unit can directly replace traditional regulators with improved efficiency and compactness. The product meets rigorous safety and electromagnetic compatibility standards, including EN 55022 and IEC/EN 62368-1 with CB report certification, suitable for digital cameras, building surveyance, office equipment, and educational electronics.
