Product Summary

The LM2575HVS-ADJ is a 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 LM2575HVS-ADJ is available in fixed output voltages of 3.3V, 5V, 12V, 15V, and an adjustable output version. The LM2575HVS-ADJ offers a high-efficiency replacement for popular three-terminal linear regulators. It substantially reduces the size of the heat sink, and in many cases no heat sink is required.
