LM2575GR-12

Voltage Regulators - DC DC Switching Regulators Overview

The TAEJIN LM2575GR-12 is a monolithic integrated circuit designed as a step-down switching voltage regulator. It provides a fixed 12V output with a guaranteed maximum output current of 1A. The device operates from an input voltage range up to 40V and utilizes a fixed 52kHz internal oscillator for timing. It requires only four external components to function, simplifying the design process. The component includes thermal shutdown and current limit protection features to ensure reliability under various operating conditions.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Fixed 12V output voltage configuration
• Integrated 52kHz fixed frequency oscillator
• Thermal shutdown and current limit protection

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation modules
• Pre-regulators for linear post-regulators
• Efficient buck converters in industrial equipment

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer marking on the component body to confirm it originates from TAEJIN Technology rather than Texas Instruments or other licensees. Ensure the suffix 'GR' corresponds to the specific package and tape-and-reel configuration required for your assembly line. Cross-reference the datasheet revision date to confirm compatibility with your design specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 12V output is required at up to 1A without the complexity of adjustable feedback networks. It is suitable for designs prioritizing simplicity and low component count over variable output flexibility. Consider the thermal performance requirements of the TO-252 package based on the expected ambient temperature and load current.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2575 family of SIMPLE SWITCHER power regulators. While originally developed by National Semiconductor and later Texas Instruments, TAEJIN Technology manufactures compatible versions under license. The LM2575 series is widely recognized for its ease of use and robust protection features in standard buck converter applications.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct pin-compatible substitutes include the TI LM2575S-12/NOPB and the onsemi LM2575TV-12. Verify that the replacement maintains the same 12V fixed output and 1A current rating. Check if the alternative manufacturer offers the same TO-252 package and moisture sensitivity level.
