R-78B5.0-1.5
Overview
The R-78B5.0-1.5 is a high-efficiency switching regulator module designed to serve as a direct drop-in replacement for standard 78 series linear regulators. It delivers a fixed 5V output at up to 1.5A from an unregulated DC input, operating with up to 94 percent efficiency. Because it generates significantly less heat than a linear regulator, it typically eliminates the need for bulky heat sinks in space-constrained designs.
Why Choose This Part
The module eliminates the requirement for external components and heat sinks, saving significant board space and reducing assembly complexity. It features integrated short-circuit protection and thermal shutdown, ensuring robust operation under fault conditions. With a wide operating temperature range from -40C to +85C, it is suitable for demanding commercial and industrial environments.
Applications
Key Specifications
Getting Started
Installation is straightforward as a 3-pin SIP module that matches the pinout of a standard LM7805; simply solder it into the existing through-hole footprint. For optimal performance, ensure input bypass capacitors are placed near the pins if the source supply is distant. No external software or programming is required for operation.
