Description
●The Bay Linear LM2575 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 LM2575 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%.
