RECOM Switching Regulator, Low Noise, ±5% Voltage Accuracy - ROF-78E Series - ROF-78E5.0-0.5SMD-R

To ensure a stable output voltage supply to your equipment, choose this switching regulator from RECOM. It converts an input voltage supply between 9 and 36V DC to a steady output voltage of 5V DC, so you can use it in your low-power devices. As the unit has an efficiency rating between 79% and 87%, you can be sure it produces minimal energy waste, eliminating the need for a heatsink. Thanks to the low output ripple and noise of 100mVp-p, your system will experience minimal electrical disturbance during the conversion process.

Features & Benefits

• Compact dimensions of 12.5 (L) x 4.5 (D) x 13.5mm (W) to easily fit on busy panels

• Voltage accuracy rating of ±5% for reliable power conversion

• Broad operating temperature range between -40°C and +85°C to withstand harsh environments

• Mean time between failures of 3,500,000 hours for Durable performance

Applications

• Medical technology

• Video game platforms

• Automotive industry

• Robotics systems

What's the difference between switching regulators and linear regulators?

Switching regulators are designed to store excess voltage in their built-in transistors while linear regulators release excess voltage as heat energy. As switching regulators have higher efficiency ratings, you'll typically find them used in high-power devices.
