RECOM Switching Regulator, 1 Output, 96% Maximum Efficiency - R-78XX Series - R-789.0-0.5

Choose this RECOM switching regulator when you need to adjust your energy source to suit your equipment. Its wide input voltage range between 11 and 32V DC means it works with many standard power supplies, giving you versatility. The device carries a load regulation rating of ±0.4%, stopping small input voltage changes from disrupting your system. Compact dimensions of 11.5 (L) x 7.55 (W) x 10.2mm (D) make this a suitable choice for installation in systems where space is at a premium.

Features & Benefits

• Low power rating of 4.5W for energy efficiency

• Simple through-hole mounting for quick installation on PCBs

• Internal short-circuit protection for minimal disruption from electrical faults

• Wide operating temperature range between -40°C and +71°C for use in challenging industrial settings

Applications

• Digital entertainment equipment

• Rail industry

Do I need to use a heat sink with this switching regulator?

No, you don't need to install a heat sink with this switching regulator. It converts between 92 and 96% of your input voltage, meaning it produces minimal levels of heat as it works.
