Procurement Notes

Verify the specific suffix M5T1G corresponds to the required reel packaging quantity of 3000 units. Confirm that the SOT-23-5 footprint matches the target PCB design constraints. Ensure the input voltage supply remains within the 2 V to 6.5 V operational limits during all transient conditions. Check thermal dissipation requirements for the 400 mA load scenario in the final assembly.

Selection Notes

Select this component when dual regulated outputs are required alongside voltage detection in a single package. The 1.5 V and 1.8 V combination suits standard digital logic families. Consider the 400 mA current limit for load requirements. The SOT-23-5 package offers space efficiency compared to larger alternatives. Verify compatibility with the system's input voltage profile before integration.
