The 10 mA output current rating and 400 µA minimum cathode current define the resistor value range for a given supply voltage. ## Tolerance and temperature — fit for the accuracy budget The ±4% initial tolerance means the output can sit anywhere from 2.390V to 2.590V at 25°C. For a 10-bit ADC with a 2.5V reference, that is about ±10 LSB of uncalibrated error — acceptable for many control and monitoring applications, but a tighter-grade reference (e.g., ±1% or ±0.5%) would be needed for measurement or instrumentation. ## TO-92-3 package — breadboard and low-volume fit The TO-92-3 through-hole package with formed leads is a legacy form factor used in prototyping and low-volume production. The through-hole footprint is larger than SMD alternatives.","metaTitle":"LM336LPR-2-5 Shunt Voltage Reference, 2.49V ±4%, TO-92-3","metaDescription":"LM336LPR-2-5 precision 2.49V shunt reference, ±4% tolerance, 10 mA output, 400 µA cathode current, 0°C to 70°C, TO-92-3.","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)","Tolerance":"±4%","Output Type":"Fixed","Mounting Type":"Through Hole","Package / Case":"TO-226-3, TO-92-3 (TO-226AA) Formed Leads","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":"TO-92-3","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"2.49V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9555","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1328b3d681daca572d2bc624f1522218.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM336LPR-2-5/alternatives.json"},"ai":{"faq":[{"question":"Is LM336LPR-2-5 obsolete or end of life?","answer":"No."},{"question":"Can LM336LPR-2-5 replace LM336Z-2.5?","answer":"Both parts are 2.49V shunt references from the same LM336 family, but the LM336LPR-2-5 is in a TO-92-3 package with formed leads (Tape & Reel), while the LM336Z-2.5 is typically in a standard TO-92 package with straight leads.
