Product Description
The Recom R-78B5.0-2.0 is a high-efficiency, through-hole switching regulator designed for demanding PCB-mounted power supply applications. This compact regulator supports input voltages ranging from 6.5V DC to 32V DC and reliably delivers a stable 5V DC output with a maximum current of 2A. Its three-pin SIP-3 package allows for straightforward through-hole installation on printed circuit boards.
Efficiency is a standout feature, with rates up to 94%, ensuring minimal energy loss as heat and eliminating the need for external heatsinks. The regulator’s narrow footprint - just 11.5mm in length, 17.5mm in height, and 8.5mm in width - makes it ideal for space-constrained designs in consumer electronics, industrial controls, and embedded systems.
Designed to operate reliably in a wide temperature range from -40°C to 70°C, the R-78B5.0-2.0 is suitable for applications exposed to harsh environmental conditions. Its built-in short-circuit protection ensures system safety by automatically restarting the regulator after tripping, minimizing downtime and risk.
Electrical noise is kept low, with a ripple and noise specification of 75mV Pk-Pk, making this regulator suitable for sensitive electronics and radio communication devices. Line regulation of ±0.5% maintains consistent output voltages, while load regulation of ±1% supports stable operation under varying load conditions.
This model achieves a Mean Time Between Failure (MTBF) of over 6.3 million hours, offering robust reliability. Certification standards include CB Report, EN 55022, and IEC/EN 62368-1. The R-78B-2.0 series is well suited to remote controls, lighting systems, vehicle dashboards, and numerous other low-voltage electronics applications.
Use cases include industrial automation, laboratory instrumentation, commercial consumer electronics, embedded system design, lighting equipment, and mobile device charging or supply modules.
