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.
