Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'QMR' indicates automotive grade qualification and tape-and-reel packaging. Confirm the '-5.0' designation ensures a fixed 5V output rather than adjustable variants. Ensure compatibility with the SO-PowerPAD thermal requirements during integration. Cross-reference the datasheet revision date to confirm pinout consistency with existing designs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V rail is required for automotive or industrial loads up to 1A. The integrated switch eliminates external inductor selection complexity compared to non-integrated regulators. Consider the 500kHz frequency for balancing efficiency and passive component size. Verify that the 42V maximum input rating aligns with the system's supply voltage profile.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2267x family of SIMPLE SWITCHER regulators, which are designed for high-efficiency DC/DC conversion. The LM22672 variant specifically targets 1A applications, distinguishing it from the 3A LM22673 and 5A LM22677 models. The 'Q' prefix denotes automotive reliability standards, while 'M' specifies the SOIC-style PowerPAD package type.
