Procurement Notes
Verify the specific grade (B, C, or D) and package type when ordering, as these determine the temperature range and exact specifications. Confirm that the DEZ suffix corresponds to the desired packaging configuration for your assembly process. Ensure compatibility with the system's input voltage requirements, which must remain within the 3 V to 15 V operational window.
Selection Notes
Select this component when system design requires a stable 5 V reference with stringent noise and drift constraints. Consider the B grade for full industrial temperature coverage or other grades if operating conditions are limited. Evaluate the low quiescent current against total system power budgets. Verify that the load capacitance requirements align with the startup settling time specifications.
