Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix QMRX indicates tape-and-reel packaging and Q denotes automotive qualification. Confirm the -5.0/NOPB designation matches the required fixed 5.0V output and lead-free status. Cross-reference the manufacturer part number with official TI documentation to ensure compatibility with specific board layouts and thermal requirements.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output at 1A is required within a 42V input system. The 500kHz frequency balances efficiency and passive size. Ensure the application demands AEC-Q100 automotive reliability. Consider alternative models if higher current or adjustable output is needed.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2267x family of SIMPLE SWITCHER regulators. It shares architectural similarities with the LM22673 and LM22676 but differs in output current ratings. The QMRX variant specifically denotes the reel-packaged version of the automotive-grade QMR device.
