RECOM Switching Regulator, 9V DC Output Voltage, 12 to 28V DC Input Voltage - R-78E Series - R-78E9.0-0.5
This switching regulator from RECOM adapts supply voltages to suit your PCB-mounted devices. Its step-down switching function works with input voltages between 12 and 28V DC, so it's compatible with many power sources. The device's precise line regulation of ±0.5% means it provides a stable 9V DC output voltage, so you GET a reliably smoothed electrical supply. For system safety, this regulator comes with integrated short-circuit protection. This feature means it resets itself automatically after electrical faults, so you can restart your machines quickly.
Features & Benefits
• Compact dimensions of 11.6 (W) x 10.4 (H) x 8.5mm (D) for a small footprint on your PCB
• Simple through-hole mounting makes installation easy
• Low maximum ripple voltage of 50mV reduces electrical noise
• Works at temperatures between -40°C and +85°C to suit demanding industrial conditions
Applications
• Video cameras
• Television displays
• Radio communication systems
• Automotive industry
Do I need to install a heatsink with this switching regulator?
No, you don't need a heatsink to use this switching regulator safely. Thanks to its maximum efficiency rate of 94%, it doesn't generate enough heat to call for an external sink.
