This is the exact voltage a designer gets — no adjustable tap, no external divider to set it. The ±4.02% tolerance means the output can sit anywhere from about 2.39V to 2.59V across the full operating range, which is a wider window than the ±1% or ±2% grades in the same family. For an 8-bit ADC reference, that 200 mV spread eats into the LSB budget; for a comparator threshold or a bias rail, it may be perfectly acceptable. ## Obsolete — PCN reality and sourcing posture STMicroelectronics lists the LM336DT as Obsolete. Sourcing now runs through independent distribution, where available stock is remnant inventory from the last production runs. Date-code provenance matters: stock surfacing years after the last-time-buy may be genuine NOS or could be pulled from a secondary market. Read the PCN before you buy, and confirm the date codes match your acceptance window. ## 8-SOIC footprint and rework considerations The 8-SOIC package matches the industry SOIC-8 land pattern. Tape & Reel (TR) is the standard shipping medium.","metaTitle":"LM336DT 2.49V Shunt Reference, ±4.02%, 8-SOIC, Obsolete","metaDescription":"STMicroelectronics LM336DT shunt voltage reference, fixed 2.49V output, ±4.02% tolerance, 10 mA output, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"STMicroelectronics","Series":"-","Package":"Tape & Reel (TR)","Tolerance":"±4.02%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Obsolete","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"10 mA","Current - Supply":"-","Current - Cathode":"400 µA","Base Product Number":"LM336","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"8-SOIC","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"2.49V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3719","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b22aab509decc69bf035f4cda3fe3f3c.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/LM336DT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/LM336DT when reusing this data.
