The L4978 is a step down monolithic power switching regulator delivering 2A at a voltage be-tween 3.3V and 50V (selected by a simple exter-nal divider). Realized in BCD mixed technology, the device uses an internalpower D-MOS transis-tor (with a typical Rdson of 0.25Ω) to obtain very high efficency and high switchingspeed. tlc227x, tlc227xa, tlc227xy advanced lincmos rail-to-rail operational amplifiers slos190 – february 1997 3–2 post office box 655303 • dallas, texas 75265 tlc2272 available options packaged devices § ta viomax at 25 °c small outline† (d) plastic dip (p) tssop‡ (pw) chip form (y) 0°cto70°c 950 µv tlc2272acd tlc2272acp c to 70 ...
