Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'NOPB' indicates lead-free and RoHS compliance. Confirm the 'T' designation corresponds to the TO-220-7 through-hole package. Ensure the '-5.0' suffix matches the required fixed 5V output specification. Cross-reference the manufacturer part number against official TI documentation to confirm availability status.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output is required at up to 3A. The TO-220-7 package provides robust thermal performance for through-hole mounting. Consider the 260kHz switching frequency for inductor size trade-offs. Verify input voltage stays within the 8V to 40V operational window.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2676 SIMPLE SWITCHER family, which offers high-efficiency step-down conversion. It serves as a direct replacement for older LM2576 series devices in many designs, offering improved efficiency and integrated features while maintaining pin compatibility for similar packages.
