It operates from a 2 V to 12 V input and supplies up to 5 mA, making it a straightforward choice for biasing an ADC reference input, a DAC, or a comparator threshold in industrial control and instrumentation circuits. The 50 ppm/°C temperature coefficient keeps the output stable across the -40°C to 85°C industrial range, which covers most factory-floor and outdoor telecom enclosures without needing a higher-grade automotive part. ## Lifecycle and compliance This part carries an Active product status and is ROHS3 compliant. No last-time-buy risk is flagged, so it can be specified into new production BOMs with confidence. The NOPB suffix confirms lead-free / RoHS3 construction, matching current assembly requirements.","metaTitle":"TI LM4120IM5-3.3/NOPB Series Voltage Reference","metaDescription":"Texas Instruments LM4120IM5-3.3/NOPB precision series voltage reference, fixed 3.3V output, ±0.5% tolerance, 50ppm/°C drift, SOT-23-5 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Tolerance":"±0.5%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","Reference Type":"Series","Voltage - Input":"2V ~ 12V","lifecycle_stage":"eol_hot","Current - Output":"5 mA","Current - Supply":"275µA","Noise - 0.1Hz to 10Hz":"20µVp-p","Noise - 10Hz to 10kHz":"36µVp-p","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"SOT-23-5","Temperature Coefficient":"50ppm/°C","Voltage - Output (Min/Fixed)":"3.3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.65","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.65000","currency":"USD"},{"qty":10,"price":"$2.38200","currency":"USD"},{"qty":25,"price":"$2.24760","currency":"USD"},{"qty":100,"price":"$1.91500","currency":"USD"},{"qty":250,"price":"$1.79808","currency":"USD"},{"qty":500,"price":"$1.57334","currency":"USD"},{"qty":1000,"price":"$1.23882","currency":"USD"},{"qty":2000,"price":"$1.20900","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d32141f906ff7ebd858f06ab2aacf7f5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the equivalent of LM4120IM5-3.3/NOPB?","answer":"A functional peer is the LM4132AMF-4.1/NOPB, which offers tighter ±0.05% tolerance and 20 ppm/°C drift, but at a 4.096 V output — not a direct pin-for-pin substitute.
