Procurement Notes
Verify that the ordering suffix matches the specific package variant required for the design. Confirm the temperature range aligns with operational requirements, as this part belongs to the extended automotive grade family. Ensure the marking code corresponds to the manufacturing site specified in the datasheet. Cross-reference the pinning configuration to avoid layout errors during PCB assembly.
Selection Notes
Select this component when a 1% reference voltage tolerance is required for precision applications. The SOT23 package offers a compact footprint suitable for space-constrained designs. Consider the thermal resistance characteristics if operating near maximum power dissipation limits. Verify compatibility with the intended cathode current range and load capacitance stability boundaries.
