DESCRIPTION
The WRN78xxM-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 tor any heat sinks with their additional
space and mounting costs.
