LM2576T-5.0/LF03

Voltage Regulators - DC DC Switching Regulators Overview

The LM2576T-5.0/LF03 is a Texas Instruments SIMPLE SWITCHER 3A step-down voltage regulator in a TO-220 package. It provides a fixed 5V output with a maximum input voltage of 40V and operates at a switching frequency of 52kHz. The device supports an output current of 3A, features internal frequency compensation for minimal external components, and includes thermal shutdown protection. It operates within a temperature range of -40°C to 125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated monolithic buck converter topology
Internal frequency compensation reduces external component count
Thermal shutdown protection circuitry
Fixed 5.0V output voltage option

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation modules
Pre-regulators for switching regulators
Efficient straight-through power supplies

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the LF03 suffix indicates lead-free compliance and specific tape-and-reel or tube packaging configuration as defined by Texas Instruments documentation. Confirm RoHS status and JEDEC moisture sensitivity level requirements for your assembly process before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part for applications requiring a fixed 5V output from inputs up to 40V. Ensure the load current does not exceed 3A and that adequate heatsinking is provided for the TO-220 package to maintain junction temperatures within the specified operating range under maximum load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2576 series of SIMPLE SWITCHER regulators. It shares functional similarities with the LM2576HV series but is limited to a 40V maximum input voltage compared to the HV variant's higher rating. The TO-220 package distinguishes it from surface-mount variants like the SOT-223 or DPAK versions.
