Overview

The TSRN 1-2450A is a non-isolated switching regulator designed to be a pin-compatible, high-efficiency replacement for 78xx series linear regulators. It provides a stable 5V output at up to 1A from an input voltage range of 6.5V to 36V. This specific 'A' variant features angular pins for right-angle mounting in space-constrained layouts.

Why Choose This Part

The module eliminates the need for external heatsinks by operating at up to 91 percent efficiency, significantly reducing the board footprint. It includes built-in filter capacitors and comprehensive protection features like short-circuit and over-temperature protection with automatic recovery.

Applications

Linear Regulator Retrofitting
Directly replaces 7805 TO-220 regulators to eliminate the need for bulky heatsinks and improve system thermal performance.
Distributed Power Architectures
Provides local 5V regulation from 12V or 24V industrial rails with 91% efficiency.
Battery Powered Equipment
Extends battery life in portable devices by reducing wasted heat compared to linear regulation, featuring a low 2mA standby current.
