LM2674LDX-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2674LDX-5.0 is a fixed-output step-down switching regulator from Texas Instruments, designed for high-efficiency voltage conversion. It operates with an input voltage range of 8 V to 40 V and provides a stable 5.0 V output at up to 500 mA. The device integrates a 0.5 A internal switch and supports a maximum switching frequency of 275 kHz. Packaged in a compact LLP-14 format, it ensures reliable performance across a wide temperature range from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates a 0.5 A power switch for simplified external component requirements
• Fixed 5.0 V output eliminates the need for external feedback resistors
• Supports high switching frequencies to minimize passive component size

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for embedded systems
• Battery-powered equipment requiring efficient voltage stepping
• Industrial control modules with wide input voltage ranges

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'LDX' against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure the 'NOPB' designation is present if lead-free compliance is required. Cross-reference the exact part number with authorized distributors to avoid counterfeit components, as minor suffix variations can indicate different packaging or material compositions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from a 40 V maximum input source. It is suitable for applications prioritizing board space efficiency due to its LLP-14 package. Consider thermal management requirements given the integrated switch capability. Verify that the load current does not exceed the 500 mA limit to maintain regulation and prevent overheating.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2674 family of simple switcher regulators. It shares architectural similarities with other members like the LM2674N but differs in package configuration. The LLP-14 package offers a smaller footprint compared to through-hole alternatives, making it ideal for dense PCB layouts while maintaining the robust protection features characteristic of the series.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM2674MX-5.0/NOPB (SOIC-8 package) or LM2674N-5.0/NOPB (MDIP package). These variants offer identical electrical performance but differ in physical mounting and thermal dissipation characteristics. Verify pinout compatibility before substitution.
