APPLICATIONS  
Add suffix “L” for 90° bend pins, for example: K7805-1000L.  
The K78xx-1000(L) 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 heatsinks with their additional space and  
mounting costs.
