Recom Switching Regulator Through Hole 3.3V DC Output Voltage 1.5A Output Current 4.95W Power R-78B3.3-1.5

Recom R-78B3.3-1.5 is a high-performance switching regulator designed for industrial and electronic applications requiring stable 3.3V DC power with 1.5A output current. This through-hole model belongs to the trusted R-78B series and delivers 4.95W power with impressive efficiency reaching 91% to minimize wasted energy and thermal load without the need for a heatsink.

Compact with dimensions of 11.5 mm length, 17.5 mm width, and 8.5 mm depth, it is ideal for densely packed circuit board layouts. It features built-in short-circuit protection that automatically resets to ensure safety and minimize downtime. The regulator operates reliably under wide input voltage conditions (4.75 to 18V DC) and across extreme temperatures from -40°C to 85°C, making it suitable for demanding industrial, laboratory, energy, and media electronics environments.

Additional benefits include a very low quiescent current at 9mA, low ripple noise at 15mV peak-to-peak, and compliance with REACH standards for environmental safety. It exhibits excellent line and load regulation of 0.2% and 0.4% respectively, ensuring stable power delivery under varying electrical conditions. The long MTBF of 3,250,000 hours supports reliable continuous operation.

Maintains output voltage within ±0.5% accuracy for effective device performance. High efficiency up to 91% reduces heat generation and increases system reliability. Compact SIP package fits easily on busy electronic boards.

Built-in short-circuit protection with automatic reset improves safety and uptime. Wide input voltage range from 4.75V to 18V DC supports diverse power sources. Low quiescent current minimizes energy consumption in standby mode.

Wide operating temperature from -40°C to +85°C supports harsh environments. Low ripple and noise output of 15mV peak-to-peak ensures stable power supply. Complies with REACH regulations for environmental safety.

This switching regulator is widely used in industrial electronics, power supply systems, energy sectors, media devices, and laboratory equipment requiring high-precision voltage conversion. It enables designers to optimize power efficiency and system reliability in compact designs.
