Overview

The RECOM R-78E3.3-0.5 is a compact, non-isolated switching regulator module designed to replace inefficient linear regulators. It provides a fixed 3.3V output with high efficiency, reducing heat dissipation and improving power system performance. This through-hole component is pin compatible with 78xx series linear regulators, making it an easy upgrade for existing designs.

Why Choose This Part

This switching regulator offers significantly higher efficiency (up to 88%) compared to linear regulators, leading to less heat generation and no need for heat sinks in many applications. Its compact SIP3 package and pin compatibility with 78xx series regulators simplify board layout and allow for straightforward upgrades. Integrated short circuit protection enhances system reliability.

Applications

General Purpose 3.3V Power Conversion

Efficiently steps down higher DC voltages (up to 28V) to a stable 3.3V, suitable for powering microcontrollers, sensors, and other digital circuitry.

Replacing Linear Regulators

Offers a direct, pin-compatible replacement for 78xx series linear regulators in applications where improved efficiency and reduced heat generation are critical.

Battery-Powered Devices

Its high efficiency (up to 88%) helps extend battery life in portable and low-power applications requiring a 3.3V supply.

Industrial and Commercial Equipment

Provides a reliable 3.3V supply for various ITE (Commercial) applications, benefiting from its short circuit protection and robust design.

Distributed Power Systems

Can be used as a point-of-load regulator to provide local 3.3V power close to the load, minimizing power losses and noise.
