LM2576DP-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2576DP-5.0 is a monolithic integrated circuit step-down switching regulator from the TAEJIN LM2576 series, designed for easy and convenient buck converter design. It features a fixed 5.0V output voltage and is capable of driving a 3.0A load with excellent line and load regulation. The device operates with a wide input voltage range and utilizes a 52kHz fixed frequency internal oscillator. It requires only four external components to function effectively.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific manufacturer designation aligns with your supply chain requirements, as component specifications may vary between original equipment manufacturers and alternative producers. Confirm package compatibility and lead times directly with authorized distributors or the supplier before finalizing procurement plans.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5.0V output is required alongside a 3.0A current capacity. Ensure the application supports a 52kHz switching frequency and verify that the input voltage range accommodates the system's supply variations. Consider the TO-252 package constraints for thermal management in the final design.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2576 family of simple switcher regulators, which are widely used for DC-DC conversion. The series includes adjustable versions and other fixed voltages like 3.3V, 12V, and 15V. The LM2576DP variant specifically denotes the surface-mount package configuration, distinguishing it from through-hole options like the TO-220.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Compatible substitutes include the LM2576T-5.0/NOPB and LM2576D2TR4-5G. Verify pinout compatibility and thermal performance characteristics when transitioning between different package types or manufacturers within the same functional family.
