The shunt topology means it behaves like a two-terminal Zener — you bias it with a resistor from the supply, and it sinks enough cathode current (minimum 20 µA) to regulate. Output current is rated at 20 mA, so it can drive a small load or feed the reference input of a converter directly. ## Package and mounting — through-hole, rework-friendly Housed in a TO-92-3 (TO-226AA) through-hole package, this reference is a direct fit for legacy board layouts and prototype builds. The three leads are on 0.1-inch pitch, easy to hand-solder or socket. No special thermal management needed at the 20 mA output level — the junction stays cool in still air at 25°C ambient.","metaTitle":"LM385BLP-2-5 Shunt Voltage Reference, 2.5V ±1.5%, TO-92-3","metaDescription":"Texas Instruments LM385BLP-2-5 is a 2.5V shunt voltage reference with ±1.5% tolerance, 20 mA output, TO-92-3 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Bulk","Tolerance":"±1.5%","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":"20ppm/°CTypical","Voltage - Output (Min/Fixed)":"2.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3700","priceTiers":[{"qty":1,"price":"$1.37000","currency":"USD"},{"qty":10,"price":"$1.22300","currency":"USD"},{"qty":25,"price":"$1.16040","currency":"USD"},{"qty":100,"price":"$0.95330","currency":"USD"},{"qty":250,"price":"$0.89108","currency":"USD"},{"qty":500,"price":"$0.78748","currency":"USD"},{"qty":1000,"price":"$0.62169","currency":"USD"},{"qty":2500,"price":"$0.58650","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/c183749392511dd90fdfbed5ba66480c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM385BLP-2-5/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM385BLP-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/LM385BLP-2-5 when reusing this data.
