Recom Switching Regulator, Through Hole, 5V dc Output Voltage, 8 → 28V dc Input Voltage, 1A Output Current, 1

Adapt your power source to suit your board-mounted hardware with this switching regulator from RECOM. It converts up to 91% of your input voltage into compatible power for your devices, minimising energy waste for high system efficiency. The converter outputs a current of 1A to provide a reliable electrical supply that's suitable for your system's basic functions. As it has compact body measurements of 11.6 (width) x 10.4 (height) x 8.5mm (depth), the component fits neatly into busy systems.

• Accepts input voltages between 8 and 28V DC for compatibility with common power supplies
• Draws a 1.5mA quiescent current when not in use for energy efficiency
• Simple through-hole mounting makes for easy installation
• Supports operating temperatures between -40°C and +85°C to work in tough industrial conditions

• Surveillance cameras
• Battery-powered devices
• Signalling systems
• Telecommunications

No, you don't need to install extra fault protection for this switching regulator because it comes with built-in short-circuit and anti-overcurrent measures. To reduce downtime, the converter automatically resets after short-circuiting.
