R-78B5.0-1.0L
Overview
The R-78B5.0-1.0L is a high-efficiency switching regulator designed as a pin-compatible drop-in replacement for standard 78 series linear regulators. It converts input voltages ranging from 6.5V to 32V down to a stable 5V output at up to 1A. By utilizing buck converter technology, it achieves up to 93% efficiency, eliminating the need for bulky heatsinks often required by linear alternatives.
Why Choose This Part
The 90-degree bent pins (L-Suffix) allow for horizontal mounting in low-profile enclosures where vertical space is limited. It features integrated short-circuit protection and thermal shutdown, ensuring robust operation without requiring external components. The 5mA low quiescent current and 93% peak efficiency significantly reduce the thermal footprint compared to linear regulators.
Applications
Key Specifications
Getting Started
As a non-isolated DC/DC converter, this module requires minimal external circuitry; however, adding input and output capacitors (typically 10uF) is recommended to further reduce ripple and noise. Ensure the input voltage stays within the 6.5V to 32V range and that the 1A maximum load is not exceeded for continuous operation. The SIP3 package allows for direct soldering into standard 0.1-inch pitch through-hole PCB layouts.
