Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the Q suffix confirms AEC-Q100 automotive qualification status against the official datasheet. Ensure the ADJ designation matches the required adjustable output topology. Confirm the MRX or MR package variant aligns with PCB assembly requirements. Cross-reference the NOPB lead-free marking with environmental compliance standards.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when automotive grade reliability is mandatory alongside a 500 mA load requirement. The wide 42 V input range suits noisy vehicle power buses. Compare against non-qualified LM22671 variants if automotive certification is unnecessary. Evaluate thermal performance in the SO-PowerPAD-8 package for the specific ambient conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2267x family of SIMPLE SWITCHER regulators. It shares architectural similarities with the LM22674 but offers lower current capacity. The family emphasizes ease of design with integrated feedback compensation. It serves as a bridge between low-power LDOs and higher-current switching solutions.
