Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB indicates lead-free compliance and RoHS standards. Confirm the N designation corresponds to the PDIP-8 package variant. Ensure the specific -12 suffix matches the required 12V fixed output specification before integration into designs requiring precise voltage rails.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V rail is required with moderate current demands. The wide input range accommodates various bus voltages. Consider the through-hole package for prototyping or applications requiring robust mechanical mounting compared to surface-mount alternatives.

Voltage Regulators - DC DC Switching Regulators Part Context

Part of the LM2574/LM2674 family of adjustable and fixed-output buck converters. Shares topology with LM2675 but differs in package and specific electrical characteristics. Designed for efficient DC-DC conversion replacing linear regulators in higher power dissipation scenarios.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2674N-12/NOPB serves as the direct lead-free equivalent. LM2674S-12 offers the same functionality in a smaller SOT-223 package. Cross-reference LM2574HV variants if input voltages exceed 40V requirements.
