APPLICATIONS
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.
