The miniature SR7805 point-of-load switching regulators provide 7.5W of output power. Operating from 4.75 to 32V-dc inputs, the regulator provides 3.3, 5, 6.5, 9, 12, or 15V-dc outputs. Claiming a 96% efficiency, the device has a 2 million-hour MTBF (mean-time-between failures). Using free-air-convection cooling allows a –40 to +85°C temperature range, and the device requires no derating or heat sinking. Additional features include low-noise operation and a tight line/load regulation. Available in a 0.45×0.3×0.4-in. miniature-SIP package.
