Description  
Derating-Graph  
The R-78Bxx-Series high efficiency switching regulators are ideally suited to replace 78xx linear regulators  
and are pin compatible. The efficiency of up to 97% 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. The L-Version with 90° pins  
allows direct replacement for laid-flat regulators where component height is at a premium. Low ripple and  
noise figures and a short circuit input current of typically only 10mA round off the specifications of this ver-  
satile converter series.
