The output is fixed at 2.5V with an initial tolerance of ±1.5% and a typical temperature coefficient of 20 ppm/°C. It can source up to 20 mA of output current and requires a minimum cathode current of 20 µA to maintain regulation. The 8-TSSOP footprint (4.40 mm width) is a common surface-mount package for board-level reference functions. ## Sourcing a discontinued precision reference Availability is limited to independent-distribution channels and surplus stock. ## Package and footprint – 8-TSSOP The 8-TSSOP package (0.173-inch body width, 4.40 mm) is a standard surface-mount form factor.","metaTitle":"LM385BPW-2-5 Shunt Voltage Reference, 2.5V Fixed, 8-TSSOP","metaDescription":"LM385BPW-2-5 shunt voltage reference: 2.5V fixed output, ±1.5% tolerance, 20 mA output, 8-TSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tray","Tolerance":"±1.5%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Obsolete","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"20 mA","Current - Supply":"-","Current - Cathode":"20 µA","Base Product Number":"LM385","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"120µVrms","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"8-TSSOP","Temperature Coefficient":"20ppm/°CTypical","Voltage - Output (Min/Fixed)":"2.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c183749392511dd90fdfbed5ba66480c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM385BPW-2-5/alternatives.json"},"ai":{"faq":[{"question":"LM385BPW-2-5 vs LM385Z-2.5 – which is better?","answer":"Both are 2.5V shunt references from the LM385 family. The LM385BPW-2-5 comes in an 8-TSSOP surface-mount package; the LM385Z-2.5 is a through-hole TO-92 part. The choice is driven by board assembly – surface-mount vs through-hole – not by electrical performance.
