DESCRIPTION
The WRN78xx-1000 Series high efficiency switching
Regulators are ideally suited to replace WRN78xx linear
regulators and are pin compatible. The efficiency of up
to 96% means that very little energy is wasted as heat
so there is no need fo any heat sinks with their additional
space and mounting costs.
