APPLICATIONS
The K78xx-1000 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.

Note:
1.C1 and C2 are required and should be fitted close to the converter pins.
2.The capacitance of C1 ,C2,C3 and C4 sees external capacitor table, it can
be increased properly if required, andtantalum or low ESR electrolytic
capacitors may also suffice.
3.No parallel connection or plug and play.
