Minimum cathode current is 20 µA, maximum output current is 20 mA, so the total current through the device plus load must stay within that ceiling. ## Package and temperature — board-fit constraints ## Sourcing reality for an obsolete part No official replacement or second-source alternate is listed on the Texas Instruments record for this exact suffix.","metaTitle":"LM385PW-2-5 Shunt Voltage Reference, 2.5V Fixed, 8-TSSOP","metaDescription":"LM385PW-2-5 is a 2.5V fixed-output shunt voltage reference in an 8-TSSOP package. ±3% tolerance, 20 mA output, 20 µA cathode current.","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":"±3%","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":"$0.2432","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c183749392511dd90fdfbed5ba66480c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM385PW-2-5/alternatives.json"},"ai":{"faq":[{"question":"What is the tolerance of LM385PW-2-5?","answer":"The initial output voltage tolerance is ±3%."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM385PW-2-5","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM385PW-2-5 when reusing this data.
