The 15 mA maximum output current limits how many loads you can drive. ## Package and mounting Housed in a SOT-23-3 package (also known as TO-236-3 / SC-59), this is a three-pin surface-mount device. The small footprint suits space-constrained layouts on automotive PCBs. The cathode is the reference output; the anode connects to ground; the third pin is the substrate (tie to ground per datasheet recommendation). ## Lifecycle and sourcing reality The LM4050QBIM3-4.1/NOPB is listed as Active with ROHS3 compliance. No end-of-life notice or last-time-buy schedule is in effect. For production BOMs, this part carries no imminent obsolescence risk.","metaTitle":"LM4050QBIM3-4.1/NOPB Shunt Voltage Reference, AEC-Q100","metaDescription":"TI LM4050QBIM3-4.1/NOPB precision shunt reference, 4.096V output, ±0.2% tolerance, 50ppm/°C drift, AEC-Q100 qualified, SOT-23-3.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Tolerance":"±0.2%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Reference Type":"Shunt","lifecycle_stage":"eol_hot","Current - Output":"15 mA","Current - Cathode":"73 µA","Noise - 10Hz to 10kHz":"93µVrms","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"50ppm/°C","Voltage - Output (Min/Fixed)":"4.096V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.0","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.00000","currency":"USD"},{"qty":10,"price":"$2.69100","currency":"USD"},{"qty":25,"price":"$2.53880","currency":"USD"},{"qty":100,"price":"$2.16300","currency":"USD"},{"qty":250,"price":"$2.03096","currency":"USD"},{"qty":1000,"price":"$1.36178","currency":"USD"},{"qty":2000,"price":"$1.32900","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f22a8d0b322e839f09010dbef7b8451d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is LM4050QBIM3-4.1/NOPB automotive qualified?","answer":"Yes, it is qualified to AEC-Q100 and belongs to the Automotive series, rated for -40°C to 125°C operation."},{"question":"Does LM4050QBIM3-4.1/NOPB require an external resistor?","answer":"Yes, as a shunt reference it needs an external resistor from the supply to the cathode to set the bias current.
