APPLICATIONS  
%
The K78xxM-1000 series high efficiency  
switching regulators are ideally suited to replace  
78xx linear regulators and are pin compatible.  
The efficiency of up to 93% means that very little  
energy is wasted as heat so there is no need for  
any heatsinks with their additional space and  
mounting costs.

Note:  
1. C1 and C2 are required and should be fitted close to the converter pins.  
2. The capacitance of C1,C2 sees external capacitor table, it can be increased properly if required, and tantalum or low ESR electrolytic capacitors  
may also suffice.  
3. No parallel connection or plug and play.
