LM2575GT-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575GT-5.0 is a step-down switching regulator IC manufactured by TAEJIN Technology Co., part of the LM2575 series. It provides a fixed 5.0V output with a guaranteed 1A load current capability. The device operates from a wide input voltage range and utilizes a 52kHz fixed-frequency internal oscillator. Designed for high efficiency, it requires only four external components for implementation. The unit features thermal shutdown and current limit protection mechanisms.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Fixed 5.0V output voltage with +/- 4% accuracy under maximum line and load conditions
• Integrated 52kHz fixed-frequency internal oscillator for simplified design
• Built-in thermal shutdown and current limit protection for system reliability
• TTL shutdown capability enabling low power standby mode operation

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation in distributed power supply architectures
• Pre-regulators for post-switching regulators
• Efficient buck converters for battery-powered systems

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation on the component marking to confirm TAEJIN origin, as this part number format is historically associated with Texas Instruments. Ensure the datasheet matches the specific electrical characteristics required for your application. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output at 1A is required with minimal external circuitry. The 52kHz switching frequency allows for the use of standard inductors. Consider the TO-220 package for through-hole mounting if thermal dissipation requirements exceed surface-mount capabilities. Verify input voltage ranges against the specific variant specifications.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2575 family of SIMPLE SWITCHER regulators. While originally developed by National Semiconductor and later Texas Instruments, TAEJIN Technology produces compatible versions. The series is characterized by its ease of use, requiring only four external components, and its robust protection features including thermal shutdown and current limiting.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct replacements include LM2575-5.0/NOPB (Texas Instruments) or LM2575T-5.0G (onsemi). These alternatives share identical pinouts and functional specifications. Verify that the substitute maintains the same 52kHz switching frequency and 1A current rating.
