Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'QMRE' indicates automotive qualification (AEC-Q100) and tape-and-reel packaging. Confirm the manufacturer part number matches the datasheet exactly. Ensure the ordering code aligns with required volume packaging formats. Cross-reference the RoHS status if environmental compliance is mandatory for the target assembly process.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required without external feedback resistors. The 500 mA rating suits moderate load applications. The wide input range accommodates various bus voltages. Verify that the thermal performance of the SO-PowerPAD-8 package meets the system's heat dissipation requirements under expected load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM22671 series of SIMPLE SWITCHER regulators. It shares topology and control features with adjustable variants like the LM22671MRX-ADJ/NOPB but provides a fixed output voltage. The family offers integrated power switches to minimize external component count compared to discrete solutions.
