The Voltage Regulator Has Evolved

Exceedingly Efficient DC Switching Regulators

Designed as a drop-in replacement for linear LM78XX and LM79XX regulators, the CUI V78, VX78, VXO78 and P78 series utilize switching technology, creating a highly compact, highly efficient alternative solution. Unlike linear regulators, these dc switching regulators do not require a heat sink, making them ideal for applications where board space is at a premium and energy efficiency is a concern. CUI’s dc switching regulator family is available with output currents of 0.5 A, 1 A, 1.5 A, and 2 A.

Features

  • Pin out compatible with TO-220 package LM78XX and LM79XX linear regulators
  • Available in SIP (straight or right angle) and SMT pin configurations
  • Compact size and high energy efficiency
  • Wide input range, up to 9~72 VDC
  • Open frame and encapsulated packages
