Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'LD' indicates the 16-WSON package variant, distinct from standard DIP or SOIC versions. Confirm the 'NOPB' designation ensures lead-free and RoHS compliance as per manufacturer specifications. Cross-reference the part number against official Texas Instruments documentation to ensure compatibility with required thermal and electrical parameters.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact surface-mount solution is required for 500 mA applications. The 16-WSON package offers significant size reduction compared to through-hole alternatives. Ensure the application input voltage remains within the 8 V to 40 V range and that the thermal environment supports operation up to 125°C.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2674 Simple Switcher family, designed for efficient step-down conversion. The LD suffix specifically denotes the small outline WSON package, differentiating it from other pin-compatible variants like the N (DIP) or M (SOIC) packages within the same functional series.
