Voltage Reference Procurement Notes

Verify that the specific suffix X indicates tape-and-reel packaging configuration when ordering. Confirm the Q prefix aligns with required automotive qualification standards for your application. Ensure the AIM3 designation matches the specified accuracy and temperature grade. Check for RoHS 3 compliance requirements against local environmental regulations. Validate the SOT-23-3 footprint compatibility during PCB layout finalization.

Voltage Reference Selection Notes

Select this component when a 2.048 V reference is required alongside automotive certification. Consider the 50 ppm/°C drift if operating across wide thermal variations. Evaluate the 15 mA load capability against downstream circuit demands. Compare noise specifications against sensitive analog front-end requirements. Assess the SOT-23-3 package size constraints relative to available board space.

Voltage Reference Part Context

This part belongs to the LM4050 family of precision shunt references from Texas Instruments. The family offers various fixed output voltages and accuracy grades.
