Features and Applications

The R-78E5.0-0.5 is part of R-78Exx series switching regulator, This module is a cost effective and energy saving therefore it reduces the use of extrenal components and its protected against shot circuits, overload and over temprature.

Its Operarting temprature ranges from -40°C to +85°C, without using heat sinks. Its miniature SIP3 case measures only 11.6 x 8.5 x 10.4mm.


  • Avoids undesired EMC radiation
  • Low Cost Switching Regulator
  • Efficiency up to 92 %
  • Short Circuit Protection
  • Pin Compatible with 78 Series Regulators
  • 5V / 500 mA Output
  • No Heat sink required
  • Input range of 4:1 extends up to 28VDC and enables the operation from 24V industry standard bus systems
  • Including 9V and 12V battery systems


  • This new lower cost module is ideal for a huge range of applications and makes no compromises with respect to quality and reliability
  • Its exceptional specifications is a viable economic alternative to a discrete solution
