Product Summary

The LM2575HVT-ADJ 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 device is available in fixed output voltages of 3.3V, 5V, 12V, 15V, and an adjustable output version. The applications of the LM2575HVT-ADJ include: (1)Simple high-efficiency step-down (buck) regulator; (2)Efficient pre-regulator for linear regulators; (3)On-card switching regulators; (4)Positive to negative converter (Buck-Boost).
