Overview

The R-78E5.0-1.0 is a 5V output, 1A switching regulator module designed to be a pin-compatible drop-in replacement for standard LM78xx series linear regulators. This SIP3 module provides high efficiency of up to 91 percent, eliminating the need for bulky heatsinks in most applications while supporting an input range of 8V to 28V.

Why Choose This Part

This module features a compact SIP3 footprint that saves board space while delivering a full 1A output current. Its high efficiency significantly reduces thermal management requirements, and integrated short circuit protection ensures system robustness in commercial and industrial environments.

Applications

Linear Regulator Replacement
Upgrading existing 7805-based designs to improve efficiency and reduce heat dissipation without changing PCB layout.
Battery Powered Systems
Extending battery life in portable electronics by minimizing conversion losses compared to linear regulators.
Industrial Control Panels
Providing stable 5V logic power from 12V or 24V industrial rails in space-constrained enclosures.

Getting Started

To use this module, replace a standard TO-220 linear regulator by matching the Pin 1 (Input), Pin 2 (GND), and Pin 3 (Output) configuration. While the switching technology reduces heat, ensure input and output capacitors are placed close to the pins as recommended by RECOM to minimize ripple and noise.
