Product Summary
The LM2576T-ADJ is a simple switche 3A step-down voltage regulator. The LM2576T-ADJ regulator is a monolithic integrated circuit that provides all the active functions for a step-down (buck) switching regulator, capable of driving 3A load with excellent line and load regulation. The LM2576T-ADJ 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 LM2576T-ADJ is simple to use and include internal frequency compensation and a fixed-frequency oscillator.
