The ±1% initial tolerance and 150 ppm/°C temperature coefficient define the accuracy budget for the system — if your ADC or comparator needs better than 1% over temperature, this part sets the floor you design from. ## Temperature range and drift — the long-term stability anchor The 150 ppm/°C drift means a 1.233 V output can shift by roughly 185 µV over a 100°C swing — within tolerance for a 10-bit ADC with a 2.5 V reference, but tight for a 12-bit system without calibration. If your design holds a calibration constant at room temperature and expects it to hold across the full range, budget that drift into the error stack. ## Package and footprint — what the SOT-23-3 means on the board The SOT-23-3 (TO-236-3, SC-59 compatible) footprint is a standard three-lead layout shared across many shunt references and small-signal transistors. No exposed pad, no thermal vias — the dissipation is handled through the leads and the small body. The base product number LM4041 covers a family of fixed and adjustable shunt references in various tolerances and packages — the DQDBZT variant is the adjustable ±1% grade in SOT-23-3. For dual-sourcing, the LM4041 family includes pin-compatible options from multiple manufacturers sharing the same SOT-23-3 footprint and 1.233 V nominal output.","metaTitle":"LM4041DQDBZT Shunt Voltage Reference, Adjustable 1.233V","metaDescription":"TI LM4041DQDBZT adjustable shunt voltage reference, ±1% tolerance, 1.233V min output, 12 mA output, -40°C to 125°C, SOT-23-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Tolerance":"±1%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Active","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"12 mA","Current - Supply":"-","Current - Cathode":"80 µA","Base Product Number":"LM4041","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"20µVrms","Operating Temperature":"-40°C~125°C(TA)","Voltage - Output (Max)":"10 V","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"150ppm/°C","Voltage - Output (Min/Fixed)":"1.233V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7200","priceTiers":[{"qty":1,"price":"$1.72000","currency":"USD"},{"qty":10,"price":"$1.54200","currency":"USD"},{"qty":25,"price":"$1.46320","currency":"USD"},{"qty":100,"price":"$1.20190","currency":"USD"},{"qty":250,"price":"$1.12356","currency":"USD"},{"qty":500,"price":"$0.99290","currency":"USD"},{"qty":1250,"price":"$0.78387","currency":"USD"},{"qty":2500,"price":"$0.73950","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/50fc5e198ec353cb298db1954beef248.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4041DQDBZT/alternatives.json"},"ai":{"faq":[{"question":"What is the LM4041DQDBZT tolerance?","answer":"The LM4041DQDBZT carries a ±1% initial tolerance on the output voltage."},{"question":"Can LM4041DQDBZT be used as a 1.225V reference?","answer":"Yes. The minimum adjustable output is 1.233 V, which is within 8 mV of 1.225 V. With two external resistors you can set it to exactly 1.225 V, within the ±1% tolerance of the part. The 80 µA minimum cathode current still applies — the bias resistor must be sized to keep the shunt in regulation at that output voltage."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM4041DQDBZT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM4041DQDBZT when reusing this data.
