The Bay Linear LM2576 contains fixed and adjustable switching voltage regulators that require a minimum of external components. All circuitry necessary to build a buck-switching regulator is included. The LM2576 is available in 3.3V; 5V, 12V & 15V fixed voltages, or an adjustable version with an output voltage range from 1.23V to 37V. The guaranteed accuracy for specified input and load conditions is 4%. The LM2576 can supply 3A with an excellent load and line regulation. Protection such as cycle-by-cycle current limiting or thermal shutdown has been designed. In standby mode, the current consumption has been minimized (200A).
