Voltage Reference Procurement Notes

Verify the complete part number including suffixes against official Texas Instruments documentation to ensure correct voltage, tolerance, and packaging specifications. Confirm AEC-Q100 qualification status if automotive compliance is required. Check for recent Product Change Notifications regarding manufacturing site or material updates before finalizing procurement orders.

Voltage Reference Selection Notes

Select this component when a high-precision, low-drift reference is needed in space-constrained automotive designs. The SOT-23-3 package offers a compact footprint compared to larger through-hole options. Ensure the circuit design accommodates the maximum shunt current limits specified in the datasheet to maintain regulation stability across the full operating temperature range.

Voltage Reference Part Context

This device belongs to the LM4050 series of precision micropower shunt voltage references from Texas Instruments. The 'Q' designation indicates automotive qualification, while 'A' denotes the tighter 0.1% accuracy grade. The 'EM3' suffix specifies the SOT-23-3 plastic package, and 'NOPB' confirms lead-free construction compliant with RoHS directives.
