RECOM Switching Regulator, 94% Efficiency, DIP Package - R-78AA-1.0 Series - R-78AA5.0-1.0SMD


Get the right level of power when and where you need it with this switching regulator from RECOM. It's designed to take an input voltage of between 6.5 and 18V DC and step it down to a smooth-and-steady output voltage of 5V DC. This makes it suitable for powering small, low-voltage appliances. As it comes in a surface-mounting 10-pin package, installing it onto your PCB takes just a jiffy.

• Remote on/off for easy control at a distance
• Compact dimensions of 9.6 (W) x 15.3 (L) x 8.8mm (D) for use where space is at a premium
• 94% efficiency cuts out heat build-up
• Mean time between failures of over 21 million hours means you can rest assured of reliable long-term performance
• Weight of 1.7g doesn't put unnecessary strain on your circuit board

Applications


• Consumer electronics
• Automotive production
• Industrial automation

Can I use this switching regulator in extreme industrial environments?


Yes, it has a broad operating temperature range between -40°C and +85°C, so you can use it in challenging conditions.

Does this product offer any protection against overcurrents?


Yes, it features continuous short-circuit protection, so it stops hazards in their tracks before downstream equipment can be damaged.
