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.
