Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'QMR' indicates automotive grade and tape-and-reel packaging. Confirm the 'NOPB' designation ensures lead-free and RoHS compliance. Cross-reference the manufacturer part number against official TI documentation to ensure authenticity and correct revision level before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when automotive qualification is mandatory for a 5V rail. It suits designs requiring a 1A load within a compact SO PowerPAD footprint. Consider the 4.5V to 42V input range for vehicle battery environments. Ensure external inductor selection supports the 500kHz frequency for optimal efficiency.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM22675 family of SIMPLE SWITCHER regulators. It shares core architecture with non-automotive variants but includes rigorous testing for automotive environmental stability. The QMR suffix specifically denotes the automotive quality tier and reel packaging format.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM22675MRE-5.0/NOPB (Non-automotive equivalent). Verify if automotive qualification is strictly required; otherwise, the standard commercial grade may suffice.
