Overview

The OKI-78SR-5/1.5-W36-C is a non-isolated switching regulator designed as a high-efficiency replacement for traditional TO-220 package 7805 linear regulators. It provides a fixed 5V output at up to 1.5A from a wide input voltage range of 7V to 36V without the need for an external heat sink. This SIP module integrates all necessary components to minimize PCB footprint while significantly reducing power dissipation and thermal issues.

Why Choose This Part

This regulator offers high efficiency which eliminates the need for bulky heat sinks, saving significant board space and assembly costs. It features a wide input range up to 36V and includes built-in short circuit protection and thermal derating performance for high reliability in harsh environments. The SIP package maintains a small 10.4mm by 16.5mm footprint while providing more than double the current capacity of standard 500mA switching modules.

Applications

Linear Regulator Replacement

Drop-in replacement for 7805 linear regulators to eliminate heat sinks and improve system efficiency.

Industrial Control Systems

Regulating 24V industrial bus voltages down to 5V for logic circuits and sensors.

Battery Powered Equipment

Extending battery life in portable devices by utilizing high-efficiency buck conversion instead of wasteful linear regulation.

Distributed Power Architectures

Local point-of-load regulation in systems with high-voltage input rails up to 36V.

Getting Started

To use this module, connect the input voltage (7-36V) to pin 1, ground to pin 2, and the 5V load to pin 3. No external capacitors are strictly required for operation, though adding 10uF ceramic capacitors at the input and output can further reduce noise in sensitive applications. Ensure the vertical or horizontal mounting orientation matches your enclosure constraints by selecting the 'C' or 'H' suffix variants respectively.
