Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2575HVT-5.0/LF03

LM2575HVT-5.0/LF03

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575HVT-5.0/LF03 is a Texas Instruments SIMPLE SWITCHER step-down voltage regulator designed for through-hole mounting in TO-220 packages. It delivers a fixed 5V output at up to 1A with an input voltage range of 4V to 60V. Operating at a typical switching frequency of 52kHz, the device integrates a monolithic synchronous rectifier and control circuitry. It supports operation across an extended temperature range from -40°C to +125°C and includes internal thermal shutdown and current limiting features.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated monolithic power switch eliminates external component requirements
Fixed 5V output option simplifies design for standard logic supplies
Internal thermal shutdown protects against overheating conditions

Voltage Regulators - DC DC Switching Regulators Applications

Distributed power supply systems
Pre-regulators for switching regulators
Battery-powered applications requiring high efficiency

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify package marking and date code alignment with official datasheets. Confirm RoHS compliance status as LF suffix indicates lead-free construction. Check for obsolescence notices or PCN updates regarding manufacturing location changes. Ensure supplier provides valid traceability documentation for industrial grade components.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 5V output is required with high input voltage capability up to 60V. The TO-220 package suits applications needing robust thermal performance without complex heatsinking. Compare against adjustable variants if flexible output voltages are needed instead of fixed regulation.

Voltage Regulators - DC DC Switching Regulators Part Context

Part of the LM2575HV family offering high-voltage input capabilities. Distinguished from surface-mount HVS variants by its through-hole TO-220 construction. Provides a cost-effective solution for medium-current buck conversion where board space allows for larger packages.
