Product Summary

The LM2575T-12 is a regulator which is monolithic integrated circuit that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 1A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5V, 12V, 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. Applications include Simple high-efficiency step-down (buck) regulator, Efficient pre-regulator for linear regulators, On-card switching regulators and positive to negative converter (Buck-Boost).
