It delivers a fixed 2.5 V output with ±3% initial tolerance and can source up to 20 mA while operating from a cathode current as low as 20 µA. The 20 mA output current rating sets the maximum load the shunt can drive. In a typical shunt configuration, the series resistor from the supply to the reference must be sized so that the total current (load plus cathode current) stays within the 20 mA ceiling and above the 20 µA minimum cathode current to maintain regulation. A 120 µVrms noise spec over 10 Hz to 10 kHz is low enough for most 8- to 12-bit ADC reference applications.","metaTitle":"Texas Instruments LM385Z-2.5/NOPB Shunt Voltage Reference","metaDescription":"Texas Instruments LM385Z-2.5/NOPB shunt voltage reference, fixed 2.5V output, ±3% tolerance, 20 mA output, TO-92-3 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Bulk","Tolerance":"±3%","Output Type":"Fixed","Mounting Type":"Through Hole","Package / Case":"TO-226-3, TO-92-3 (TO-226AA)","Product Status":"Active","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":"TO-92-3","Temperature Coefficient":"150ppm/°C","Voltage - Output (Min/Fixed)":"2.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1d0994349221fdb4ebddbdb4113bddcd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM385Z-2.5%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"What is the tolerance of LM385Z-2.5/NOPB?","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/LM385Z-2.5-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM385Z-2.5-NOPB when reusing this data.
