Product Summary

The lm2575t-12v is a 1A Step-Down Voltage Regulator. It provides all the active functions for a step-down (buck) switching regulator, capable of driving a 1A load with excellent line and load regulation. The lm2575t-12v is available in fixed output voltages of 3.3V, 5V, 12V, 15V, and an adjustable output version. Requiring a minimum number of external components, the regulator lm2575t-12v is 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, Positive to negative converter (Buck-Boost).
