It is designed for applications requiring a stable reference voltage, such as A/D converter references, power-supply monitoring, and comparator threshold setting. ## Parametric limits for the BOM The LM336BDT delivers up to 10 mA output current and requires a minimum 400 µA cathode current to regulate. The ±2% tolerance means the output voltage can vary between 2.44 V and 2.54 V at 25°C — adequate for general-purpose references but not for precision measurement where tighter tolerance (0.5% or better) is needed. The shunt topology means it behaves like a Zener diode: a series resistor sets the bias current, and the load current subtracts from the cathode current budget. ## Obsolete — sourcing reality The LM336BDT is listed as obsolete by STMicroelectronics. For new designs, a current-production shunt reference from the same family (e.g., LM336 series in a different package variant or a modern alternative from another manufacturer) should be evaluated.","metaTitle":"LM336BDT STMicroelectronics 2.49V Shunt Reference, ±2%","metaDescription":"LM336BDT is an obsolete 2.49V shunt voltage reference from STMicroelectronics. ±2% tolerance, 10 mA output, 400 µA cathode current. 8-SOIC package, 0°C to 70°C.","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) Cut Tape (CT)","Tolerance":"±2%","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":"$2.4600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/31dfd94bcbb8d1fcb0f7426057908b5f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for LM336BDT?","answer":"No official replacement is listed by STMicroelectronics.
