Voltage Reference Procurement Notes
Verify the specific suffix X2.0 indicates the 2.048V output variant during sourcing. Confirm AEC-Q100 compliance requirements match target automotive standards. Check RoHS status against environmental regulations. Ensure SOT-23-3 footprint compatibility with PCB layout. Validate operating temperature range suitability for final assembly environment.
Voltage Reference Selection Notes
Select this component when automotive qualification is mandatory alongside precise voltage referencing. Compare initial accuracy and temperature drift against system tolerance requirements. Evaluate power consumption constraints relative to battery life expectations. Consider physical size limitations imposed by the SOT-23-3 package dimensions in dense layouts.
Voltage Reference Part Context
This part belongs to the LM4050 family of micropower shunt voltage references from Texas Instruments.
