R-78E5.0-1.0
High-efficiency 5W non-isolated buck regulator, 6.5-32V input, 5V/1A output in SIP-3 package.
Product Overview
Description
The R-78E5.0-1.0 from Recom is a high-efficiency switching regulator designed as a direct replacement for 7805 linear regulators. The 6.5-32V input range accommodates common industrial voltages including 12V, 24V, and 28V systems. With efficiency up to 95%, it eliminates the need for heatsinks even at full 1A output current. The compact SIP-3 package (11.5 x 8.5 x 17.5mm) is pin-compatible with standard 78xx regulators, allowing easy upgrades to existing designs. Unlike linear regulators that dissipate excess voltage as heat, the switching topology maintains high efficiency across the input range. The regulator includes built-in protection against short circuits, overcurrent, and overtemperature. Operating temperature range of -40°C to +85°C makes it suitable for industrial environments. The R-78E5.0-1.0 is an economical solution for point-of-load regulation in distributed power systems.
