The LM2575 15V 1A Step-Down Voltage Regulator is a monolithic integrated circuit that provides all the active functions for a step-down (buck) switching regulator, capable of driving a 1A load with excellent line and load regulation. This device is available in the fixed output voltage of 15V and an adjustable output version. Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation and a fixed-frequency oscillator. The LM2575 offers a high-efficiency replacement for the popular three-terminal linear regulator. Because of its high efficiency, the copper traces on the printed circuit board are normally the only heat sinking needed
