Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2575T-5.0/LF04

LM2575T-5.0/LF04

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575T-5.0/LF04 is a Texas Instruments SIMPLE SWITCHER® 1A step-down voltage regulator in a TO-220-5 through-hole package. It provides a fixed 5.0V output with a maximum load current of 1A. The device supports an input voltage range from 4V to 40V and operates at a typical switching frequency of 52kHz. It features internal frequency compensation, thermal shutdown, and cycle-by-cycle current limiting.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated buck topology with minimal external component requirements
Built-in thermal shutdown and cycle-by-cycle current limit protection
Fixed 5.0V output with ±4% accuracy under specified conditions

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for digital circuits
Pre-regulator stages for downstream linear regulators
Battery-powered systems requiring efficient step-down conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the LF04 suffix against the official datasheet to confirm it denotes lead-free RoHS compliance without altering electrical parameters. Confirm the TO-220-5 package type matches your PCB footprint requirements. Ensure the fixed 5.0V output aligns with your system design needs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part for applications requiring a robust 1A buck converter with through-hole mounting. It serves as a direct replacement for standard three-terminal linear regulators where reduced heat dissipation is critical. Consider the 52kHz switching frequency for EMI constraints and verify input voltage stability within the 4V to 40V range.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2575 family of SIMPLE SWITCHER regulators. It shares core architecture with variants like LM2575T-3.3/NOPB and LM2575T-12 but differs in fixed output voltage. The TO-220-5 package distinguishes it from surface-mount versions like the LM2575S series.
