The ±1% tolerance on the reference voltage gives tighter regulation than the standard TL431's ±2% grade, which matters when the feedback divider sets the output of a switching supply or a linear regulator. ## Output current and cathode current limits Rated for 100 mA continuous output current, with a minimum cathode current of 600 µA to maintain regulation. The 100 mA ceiling defines the load the shunt can sink before the reference voltage drifts; for higher loads, an external pass transistor is needed. The 600 µA minimum means the bias resistor must be sized to keep at least that current flowing through the device at all times. That excludes automotive under-hood, industrial motor drives, or outdoor telecom cabinets where the ambient regularly exceeds 70°C. For extended temperature ranges, look at the TL432B or TL431A variants rated to 125°C.","metaTitle":"TL432ACDBZRG4 Adjustable Shunt Reference, ±1% Tolerance","metaDescription":"Texas Instruments TL432ACDBZRG4 adjustable shunt voltage reference, 2.495V min output, ±1% tolerance, 100 mA output, SOT-23-3 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Tolerance":"±1%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"100 mA","Current - Supply":"-","Current - Cathode":"600 µA","Base Product Number":"TL432","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"0°C~70°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":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2e8567ad04842692d5fb8309c69e90b6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL432ACDBZRG4/alternatives.json"},"ai":{"faq":[{"question":"Is TL432ACDBZRG4 the same as TL431?","answer":"The TL432ACDBZRG4 is functionally identical to the TL431 in the same SOT-23-3 package, but with a tighter ±1% tolerance versus the TL431's typical ±2% grade.
