It uses a two-terminal shunt topology and comes in a SOT-23-3 package. ## Shunt topology — what it means for your bias network The load current plus cathode current must exceed 80 µA to maintain regulation. Total current through the device must stay under 15 mA. ## Active production, no obsolescence worry No NRND or EOL flags. It's also ROHS3 compliant, so it passes lead-free assembly requirements without exemption paperwork. For a BOM line that needs a stable 5V reference, this part is a safe choice for both new designs and ongoing production — no last-time-buy scheduling needed.","metaTitle":"TL4050C50IDBZT Shunt Voltage Reference, 5V ±0.5%, SOT-23-3","metaDescription":"TI TL4050C50IDBZT precision 5V shunt reference, ±0.5% tolerance, 50ppm/°C drift, SOT-23-3.

For a drop-in shunt replacement, stay within the TL4050 family at the same voltage and tolerance grade."},{"question":"What is the difference between shunt and series voltage reference?","answer":"A shunt reference (like this TL4050) is a two-terminal device that regulates voltage by shunting current to ground through a series resistor — it behaves like a precision Zener. A series reference has three terminals (input, output, ground) and regulates by varying its own series pass element; it typically offers lower quiescent current and better accuracy, but needs a supply voltage above the output. The TL4050C50IDBZT is a shunt type, so it's simpler to bias but requires careful resistor selection to stay within the 80 µA to 15 mA cathode current range."},{"question":"Is the TL4050C50IDBZT compatible with bipolar ADC inputs?","answer":"Yes, it can be used to generate a precision 5V reference for a bipolar ADC that accepts a 5V reference input. The 93 µVrms noise and 50 ppm/°C drift are adequate for 12-bit to maybe 14-bit systems, depending on your noise budget. For higher-resolution or lower-drift requirements, consider a series reference with lower noise and drift."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TL4050C50IDBZT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TL4050C50IDBZT when reusing this data.
