RECOM Switching Regulator, 7 to 28V DC Input Voltage, 3.3V DC Output Voltage - R-78E-1.0 Series - R-78E3.3-1.0

Convert your power supply to suit attached appliances with this switching regulator from RECOM. As it has a wide input voltage range of 7 to 28V DC, it's a versatile choice that works with many standard electrical supplies. With output line regulation accurate to ±1%, the device gives you a consistent power connection to support reliable performance. This converter includes overcurrent and short-circuit protection to keep your system safe from potentially hazardous faults.

Features & Benefits

• Output voltage of 3.3V DC lets you keep using low-voltage hardware with more powerful supplies
• PCB through-hole mounting makes for easy installation
• Compact dimensions of 11.6 (length) x 8.5 (width) x 10.4mm (height) maximises the mounting space on your board
• Converts up to 87% of input voltage to reduce energy wastage

Applications

• Gaming consoles
• Telecommunications industry
• Industrial computers

Do I need external components to use this regulator?

You don't need any external components to use this converter. If your power supply is rated at higher than 26V, you should use an input capacitor with the device to reduce disruption from EMI.
