Noise from 10 Hz to 10 kHz is specified at 60 µVrms typical, low enough for most 8- to 12-bit ADC reference or comparator threshold applications. The 15 µA minimum cathode current allows the reference to operate from high-impedance bias networks without dropping out. ## Through-hole TO-92-3 package Housed in a TO-226-3 / TO-92-3 (TO-226AA) through-hole package with a supplier device package designation of TO-92-3. The three leads are spaced on 0.100-inch pitch, compatible with standard prototyping boards and socket strips.","metaTitle":"LM385BLPE3-1-2 Shunt Voltage Reference, 1.235 V Fixed, ±1%","metaDescription":"Texas Instruments LM385BLPE3-1-2 shunt voltage reference, 1.235 V fixed output, ±1% tolerance, 20 ppm/°C typical drift, 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":"±1%","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":"15 µA","Base Product Number":"LM385","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"60µVrms","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"TO-92-3","Temperature Coefficient":"20ppm/°CTypical","Voltage - Output (Min/Fixed)":"1.235V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9600","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM385BLPE3-1-2/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM385BLPE3-1-2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM385BLPE3-1-2 when reusing this data.
