Procurement Notes

Verify the specific grade (standard or A grade) required for your application tolerance needs. Confirm the SOT23-3 package availability matches your PCB layout constraints. Ensure the operating environment stays within the -40°C to +85°C industrial range to maintain specified performance characteristics. Check datasheet details for capacitive load stability requirements before finalizing design integration.

Selection Notes

Select this component when a fixed 2.5V reference is needed with minimal quiescent current. Consider the ±2% or ±1% tolerance based on circuit sensitivity. The SOT23-3 package is ideal for compact designs. Evaluate if the industrial temperature range meets your environmental requirements compared to commercial grades.
