APPLICATIONS  
%
Upgraded K78xx-2000(L) series switching  
regulators are ideal replacement for K78xx  
linear regulators and LDOs. The efficiency of  
up to 92% means that very little energy is  
wasted as heat so there is no need for any  
heat sinks with their additional space and  
mounting costs. They are widely used in  
industrial control, instrumentation, and electric  
power applications.
