Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2575HVT-3.3/LF03

LM2575HVT-3.3/LF03

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575HVT-3.3/LF03 is a Texas Instruments SIMPLE SWITCHER step-down voltage regulator designed for through-hole mounting in a TO-220 package. It delivers a fixed 3.3V output at up to 1A with an input voltage range of 4V to 60V. The device operates within a temperature range of -40°C to 125°C and features a switching frequency of 58 kHz. It includes internal frequency compensation, a 150mA standby current, and thermal shutdown protection.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated high-voltage power switch rated for 60V input
Fixed 3.3V output option with 1A continuous current capability
Built-in thermal shutdown and current limit protection
Requires minimal external components for implementation

Voltage Regulators - DC DC Switching Regulators Applications

Distributed power supply systems
Pre-regulator circuits for switching regulators
Battery chargers
Simple point-of-load regulation

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix LF03 against the manufacturer's official datasheet to confirm lead-free compliance and RoHS status. Confirm availability as distribution channels may list this component as obsolete or out of stock. Ensure the through-hole TO-220 package matches your PCB footprint requirements before ordering.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 3.3V output is required from a high-voltage source up to 60V. It is suitable for applications needing through-hole installation and robust thermal performance. Consider the LM2575HVS series if surface-mount packaging is preferred instead of the TO-220 form factor.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2575 family of SIMPLE SWITCHER regulators. It provides a cost-effective solution for step-down conversion. The HVT designation indicates a high-voltage variant capable of handling inputs up to 60V, distinguishing it from standard low-voltage versions.
