R-78B Data Sheet

COO (Country of Origin):: TW

R78Bxx 1.0 Series Switching Regulator

The Recom R-78Bxx series are highly efficient, non-isolated switching regulators. They offer a high-quality product at a low cost in production quantity. Their low-profile design enables them to be used in numerous applications from distribution supply systems, controllers and sensors, robotics, medical and telecommunications.

The convertor has a high-voltage input range and there is no need for heat sinks, due to little energy being wasted. It has a wide input range with short circuit protection and no external components are needed to work efficiently.

Features and Benefits

• Low profile

• Pin compatible with LM78xx linear regulators

• High efficiency, non-isolated, no need for heatsinks

• Requires no external components

• Fully protected for short circuit

• Low ripple and noise

• Compact size, ensuring space saving

Note

Derate output when operating temperature above 71°C.
