PART NUMBER: V78XX-500 series  
DESCRIPTION: DC switching regulator, non-isolated  
features  
description  
·efficiency up to 96%  
·no need for heatsinks  
·wide input range  
·short circuit protection  
·thermal shutdown  
·low ripple and noise  
·pin compatible to LM78XX  
series  
The V78XX series of switching regulators are  
designed to replace 78XX linear regulators,  
with the objective of drop-in replacement  
without the need for a heatsink, because the  
V78XX series features high efficiency under  
all line conditions. Built-in short-circuit and  
over-temperature protections ensure very  
rugged operations. Additionally, low ripple  
and noise performance make the parts useful  
in a wide range of applications.
