The Texas Instruments LM4051CEM3X-1.2/NOPB is a precision shunt voltage reference delivering a fixed 1.225 V output with ±0.5% initial accuracy.
That 12 mA ceiling sets the load budget: a typical ADC reference input draws under 1 mA, leaving headroom for a resistive divider or pull-up.
Design engineers need exact accuracy to ensure the reference meets circuit precision requirements.
Sourcing buyers need to quickly locate available inventory to avoid production delays.
Volume pricing directly impacts BOM cost and sourcing decisions for procurement teams.
Lifecycle status determines long-term availability and risk for ongoing production.
Engineers and buyers need drop-in replacements or cross-references for multi-sourcing or EOL situations.
Maintenance techs and designers need physical fit details for board layout and replacement.
