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.
