The shunt architecture means it behaves like a precision Zener diode — you bias it with a resistor from the supply rail and it sinks enough current to hold the output at 10V, up to 15 mA of load current. ## Where the 150ppm/°C drift lands you The 150ppm/°C temperature coefficient is the D-grade spec — the cost-optimized tier in the LM4040 family. That's fine for an 8-bit ADC reference or a regulator bias rail, but if you're feeding a 12-bit converter with a 10V full-scale, the drift eats into your LSB budget. For tighter accuracy, step up to the A-grade (100ppm/°C) or the E-grade (30ppm/°C) variants in the same package. That means no last-time-buy notice to watch, no end-of-life scramble, and the part is still being manufactured by TI. The SOT-23-3 package is a standard footprint across the LM4040 family, so if you later need tighter tolerance, the pad layout stays the same. ## Sourcing and quoting for the BOM line For volume commitments, the active lifecycle means TI's own channel is also an option, but the independent route gives you flexibility on date codes and split orders.","metaTitle":"LM4040DIM3X-10/NOPB Shunt Voltage Reference, 10V ±1%","metaDescription":"Texas Instruments LM4040DIM3X-10/NOPB precision shunt reference, fixed 10V output, ±1% tolerance, 150ppm/°C drift, SOT-23-3, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Tolerance":"±1%","Output Type":"Fixed","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":"15 mA","Current - Supply":"-","Current - Cathode":"110 µA","Base Product Number":"LM4040","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"180µVrms","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"150ppm/°C","Voltage - Output (Min/Fixed)":"10V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2382","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/db47fc1a31c797b619d88478be755429.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4040DIM3X-10%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"What is the equivalent or cross reference for LM4040DIM3X-10/NOPB?","answer":"The LM4040 family has multiple tolerance grades in the same SOT-23-3 footprint.
