Voltage Reference Procurement Notes

Verify the specific suffix 'Q1' confirms AEC-Q100 automotive qualification status. Confirm the 'T2.5' designation matches the required 2.5 V output voltage level. Ensure the 'MF' package code corresponds to the SOT-23-5 form factor needed for your PCB layout. Cross-reference the full part number against the manufacturer's latest datasheet to confirm active production status and any recent process change notifications.

Voltage Reference Selection Notes

Select this component when automotive certification is mandatory for the application environment. Choose this part if the design requires a 2.5 V reference with 0.4% initial accuracy tolerance. Consider this option for systems operating between -40°C and +125°C where thermal stability is critical. Opt for this device when a low-profile SOT-23-5 footprint is necessary for assembly constraints.
