Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'QMRE' indicates AEC-Q100 automotive qualification and reel packaging. Confirm that the 'ADJ' designation requires external resistor programming for the target voltage. Ensure the SO-PowerPAD-8 thermal pad soldering meets IPC standards for reliable heat dissipation during high-load operation.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when an adjustable output within the 4.5 V to 42 V input range is required. It is suitable for designs needing 500 mA continuous current with automotive grade reliability. Consider the fixed 500 kHz frequency for balancing efficiency and passive component size compared to other switching frequencies.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM22671 series of Simple Switcher regulators. It shares the same core architecture as fixed-output variants but allows flexible voltage setting via external feedback resistors. The QMRE suffix distinguishes it as an automotive-grade, tape-and-reel packaged version of the standard LM22671MR.
