It delivers up to 20 mA output current while drawing only 100 µA supply current — a combination that suits it for biasing sensor front-ends, supplying ADC reference rails, or setting a stable voltage for a microcontroller's analog peripherals in under-hood and engine-bay environments. The ±0.2% initial tolerance and 75 ppm/°C temperature coefficient keep the output within tight bounds across the full -40°C to 125°C operating range. ## What the ratings mean for the BOM The 20 mA output rating is the maximum the reference can source while maintaining regulation. The 100 µA quiescent current is the reference's own draw. ## Lifecycle and sourcing Listed as Active in production with ROHS3 compliance. No end-of-life notice or last-time-buy window is in effect.","metaTitle":"LM4128BQ1MF3.3/NOPB Voltage Reference, 3.3V ±0.2%, SOT-23-5","metaDescription":"TI LM4128BQ1MF3.3/NOPB series voltage reference, 3.3V fixed output, ±0.2% tolerance, 20 mA output, 100 µA supply, -40°C to 125°C, AEC-Q100.","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":"SC-74A, SOT-753","Reference Type":"Series","Voltage - Input":"3.7V ~ 5.5V","lifecycle_stage":"eol_hot","Current - Output":"20 mA","Current - Supply":"100µA","Noise - 0.1Hz to 10Hz":"310µVp-p","Operating Temperature":"-40°C ~ 125°C (TJ)","Supplier Device Package":"SOT-23-5","Temperature Coefficient":"75ppm/°C","Voltage - Output (Min/Fixed)":"3.3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.81","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.81000","currency":"USD"},{"qty":10,"price":"$3.42100","currency":"USD"},{"qty":25,"price":"$3.23400","currency":"USD"},{"qty":100,"price":"$2.80290","currency":"USD"},{"qty":250,"price":"$2.65912","currency":"USD"},{"qty":500,"price":"$2.38602","currency":"USD"},{"qty":1000,"price":"$1.52550","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d0a8321878fcc5289c7be83212ba7ad8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What compliance documentation is available for LM4128BQ1MF3.3/NOPB?","answer":"The part is ROHS3 Compliant.
