Description
The R-78xx-1.0 series high efficiency switching regulators are ideally suited to replace 1 Amp 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 heat sinks with their additional space and mounting costs. Low ripple and noise figures and a short circuit input current of typically only 10mA round off the specifications of this versatile converter series.
