RECOM Switching Regulator, Through-Hole Mounting, 1A Output Current - R-78-1.0 Series - R-781.8-1.0


Looking for a power conversion solution that's safe for use in medical applications? You're in safe hands with this RECOM switch regulator. It takes a wide input range from 4.75 to 18V DC and delivers a steady output voltage of 1.8V, ensuring a reliable power source for your critical equipment. Thanks to compact dimensions of 11.5 (L) x 7.55 (W) x 10.2mm (D) size, it won't take up much space in your setup.

Features & Benefits


• Low ripple and noise of 20mV Pk-Pk keeps EMI to a minimum
• Efficiency of 82% means little energy is lost during conversion, so you won't need a heat sink
• Performs without a glitch in a challenging temperature range between -40°C and +85°C

Applications


• Renewable energy plants
• Automotive industry
• Telecommunications networks

How does this regulator handle unsteady input voltage?


This switching regulator delivers line regulation of 0.2%. This means that even with fluctuating input voltage, it's able to maintain steady output.

How reliable is this switching regulator?


As it has a mean time between failures of over 13 million hours at +25°C, you can depend on smooth and consistent performance over the long term.
