RECOM Switching Regulator, 5V DC Output Voltage, 6.5 to 32V DC Input Voltage - R-78B-2.0 Series - R-78B5.0-2.0
Rest assured that your power supply is compatible with your equipment with the help of this switching regulator from RECOM. With its wide input voltage range between 6.5 and 32V DC, it's a practical way of adapting many common power supplies to work safely with your low-voltage devices. As the unit achieves efficiency rates of up to 94%, it minimises energy lost as heat and doesn't need a heatsink to work safely. The device's narrow dimensions of 11.5 (width) x 17.5 (height) x 8.5mm (depth) mean it has a small footprint and fits easily into busy PCB-mounted systems.
Features & Benefits
• Built-in short-circuit protection automatically restarts regulator after tripping for minimal downtime
• Simple through-hole mounting for fast installation on PCBs
• Line regulation of ±0.5% so you GET consistent output voltages
• Wide operating temperature range from -40°C to +70°C, so it withstands harsh environments
Applications
• Remote controls
• Lighting systems
• Vehicle dashboards
• Consumer electronics
Can I use this switching regulator for my radio application?
Yes, this converter is suitable for radio applications as its ripple and noise rating of 75mV means it doesn't produce much electrical noise. This helps minimise disruption to radio communications.
