The device can sink up to 100 mA through the cathode, enough to drive the optocoupler LED in a feedback loop or to pull down a pass transistor's base drive in a linear regulator. Below that the device drops out of regulation, so the bias resistor from cathode to supply must be sized to maintain at least 1 mA through the part over all load and line conditions. ## Industrial temperature range, obsolete lifecycle The SOT-23-3 footprint is a direct drop-in for many designs that need the smaller board area.","metaTitle":"TL432QDBZT Adjustable Shunt Reference, ±2.2%, SOT-23-3","metaDescription":"TL432QDBZT adjustable shunt voltage reference, ±2.2% tolerance, 100 mA output, SOT-23-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Tolerance":"±2.2%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Obsolete","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"100 mA","Current - Supply":"-","Current - Cathode":"1 mA","Base Product Number":"TL432","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"-40°C~125°C(TA)","Voltage - Output (Max)":"36 V","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"2.495V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/99b53f28cf28b982a16c2a9ac87cd6e9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL432QDBZT/alternatives.json"},"ai":{"faq":[{"question":"What is the tolerance of TL432QDBZT?","answer":"The TL432QDBZT has a ±2.2% tolerance on the reference voltage, which is tighter than the standard 2.5% grade found on many TL431 variants."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TL432QDBZT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TL432QDBZT when reusing this data.
