Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix QMR indicates the tape and reel packaging format distinct from tube variants. Confirm the -5.0 designation ensures the fixed 5V output rather than adjustable versions. Ensure the NOPB suffix confirms lead-free and RoHS compliance status before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when automotive qualification is mandatory for buck converter applications. The 500 mA output current suits low-power logic or sensor rails. The wide input voltage range accommodates vehicle battery fluctuations. Verify that the fixed 5V output meets system requirements without external feedback adjustments.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM22674 family of SIMPLE SWITCHER regulators. It shares topology with the LM22673 but offers lower current capacity. The QMR variant specifically denotes the SO-PowerPAD-8 package in tape and reel form, distinguishing it from the standard MR tube packaging.
