LM2576T-5.0 IC REG BUCK 5V 3A TO220-5

The LM2576T-5.0 is a monolithic integrated circuit that provides all the active functions for a step-down (buck) switching regulator. This device is capable of driving a 3A load with excellent line and load regulation. Requiring a minimum number of external components, this regulator is simple to use and includes internal frequency compensation and a fixed-frequency oscillator. The LM2576T-5.0 series offers a high-efficiency replacement for popular three-terminal linear regulators. It substantially reduces the size of the heat sink, and in some cases, no heat sink is required. A standard series of inductors optimized for use with the LM2576T-5.0 are available from several different manufacturers.

This feature greatly simplifies the design of switch-mode power supplies. The LM2576T-5.0 features include a guaranteed ±4% tolerance on output voltage within specified input voltages and output load conditions, and ±10% on the oscillator frequency. External shutdown is included, featuring typically 50 μA standby current. Self-protection features include a two-stage frequency reducing current limit for the output switch and an overtemperature shutdown for complete protection under fault conditions. The TO220-5 package provides a convenient mounting option for efficient heat dissipation. Key applications include efficient pre-regulator for linear regulators, on-card switching regulators, positive to negative converters, and simple buck regulators.
