DESCRIPTION The WRN78xx-1000 Series high efficiency switching Regulators are ideally suited to replace 78xx 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.
