SR Series

0.5A SR05 & 1A SR10 series 3 pin switching regulators

The SR series switching regulators are pin compatible, efficient, replacement for the 78XX positive linear regulators. With efficiency up to 95%, very little energy is wasted as heat so there is no requirement for a heatsink, giving significant space saving and providing more flexibility for the PCB design.

These non-isolated DC-DC converters offer a simple step-down voltage conversion and good line/load regulation, low ripple & noise with a low quiescent current (no load) of 10mA. The SR provide a low-cost point of load (POL) solution for portable & battery-operated equipment and a multitude of other applications.
