Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free status and RoHS compliance as per manufacturer specifications. Ensure the 'MX' designation matches the required SOIC-8 surface mount package variant. Cross-reference the datasheet revision date to confirm technical parameters align with your design requirements before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12 V output is required from a 40 V maximum input source. It is suitable for applications needing moderate current up to 500 mA where board space is limited by the SOIC-8 package. Consider alternative packages if through-hole mounting or higher current capacity is necessary for the specific system design.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2674 series of SIMPLE SWITCHER regulators, designed for high-efficiency DC-DC conversion. The series offers various fixed output voltages and packaging options to accommodate diverse power management needs in compact electronic designs while maintaining robust performance across industrial temperature ranges.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2674MX-ADJ/NOPB provides adjustable output instead of fixed 12 V. LM2674N-12/NOPB offers the same electrical characteristics but uses an MDIP through-hole package rather than surface mount.
