RECOM Switching Regulator, 5V DC Output Voltage, Surface Mounting - R-78AA-0.5 Series - R-78AA5.0-0.5SMD

Need a stable power distribution device for the components on your PCB? Choose this switching regulator from RECOM. It accepts input voltages between 6.5 and 32V DC and steps them down to a steady output voltage of 5V DC for the reliable operation of your low-power devices. Thanks to its Compact dimensions of 15.3 (L) x 9.6 (W) x 8.8mm (H), this s a practical choice for installation in crowded systems. Its plastic housing is resistant to impact and abrasion for durability in harsh environments. As this material is also non-conductive, it helps protect users against electric shocks.

Features & Benefits

• Mean time between failures of up to 29,253,000 hours at +25°C for reliability

• Wide operating temperature range between -40°C and +85°C for use in demanding conditions

• Light weight of 2.7g puts minimal strain on your board

• High efficiency of 86 to 94% for minimal power loss

Applications

• Aerospace industry

• Laptop and desktop computers

Is this switching regulator protected against electrical hazards?

Yes, this switching regulator features built-in short circuit protection to prevent damage in the event of a fault.
