Product Summary

The LM2575T-5.0 is a Step-Down Voltage Regulator. The LM2575T-5.0 provides all the active funtions for a step-down switching regulator. The LM2575T-5.0 features an output voltage which is adjustable from 1.23V to 37V and is capable of driving a 3A load with excellent line and load regulation. The LM2575T-5.0 offers a high efficiency replacement for popular three-terminal adjustable linear regulators. The LM2575T-5.0 substantially reduces the size of the heat sink and in many cases no heat sink is required. Applications include simple high-efficiency step-down regulator, efficient pre-regulator for linear regulators, on-card switching regulators, positive to negative convert, isolated flyback converter using minimum number of external components and negetive boost converter.
