Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the M3 suffix indicates specific qualification or material compliance standards required by your application. Confirm that the TSOT-23-THIN-6 physical dimensions match your PCB footprint constraints. Ensure the 42V maximum input rating aligns with your system's transient voltage specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a single-output buck regulator is needed for 42V automotive systems. Compare against the LM2842XQM series if different current ratings are required. Consider the fixed 1.25MHz frequency for EMI management and ensure the 600mA limit suits the load profile.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2842 family of SIMPLE SWITCHER regulators. It shares architectural similarities with the LM2841 but offers higher current capability. The YQMK designation specifies the automotive-grade variant with specific thermal and electrical characteristics distinct from standard commercial versions.
