The shunt architecture means it behaves like a Zener diode — it regulates by sinking current through the cathode, which simplifies biasing in split-supply or single-supply rails. ## Package and rework — 8-SOIC is a friendly footprint The 1.27 mm pin pitch gives good clearance for inspection and touch-up under a hot-air station. ## Output current and cathode bias — the practical limits The LM336BDR-2-5 can source up to 10 mA from the output pin, which is enough to bias a single ADC reference input or a comparator threshold divider. The minimum cathode current is 400 µA — the bias resistor from the supply rail to the cathode must be sized to keep at least this much current flowing at all times, otherwise the reference drops out of regulation. For a 5V rail, a 6.2 kΩ resistor sets the bias current near 400 µA; a lower value increases headroom for load transients.","metaTitle":"LM336BDR-2-5 Texas Instruments Shunt Reference, 2.49V ±2%","metaDescription":"Texas Instruments LM336BDR-2-5 precision shunt voltage reference, fixed 2.49V output, ±2% tolerance, 8-SOIC package, 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":"±2%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Active","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":"$0.3566","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1328b3d681daca572d2bc624f1522218.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM336BDR-2-5/alternatives.json"},"ai":{"faq":[{"question":"Can LM336BDR-2-5 replace a LM336D?","answer":"Both are part of the LM336 family with the same 2.49V output and shunt architecture, but the LM336D typically comes in a TO-92 through-hole package.
