Output voltage is set with two external resistors and can be adjusted up to 36 V. The part sinks up to 100 mA and requires a minimum cathode current of 700 µA to maintain regulation. The 100 mA output current is enough to drive an optocoupler LED in a feedback loop, bias a small-signal transistor, or supply a low-power load. The 700 µA cathode current sets the floor for the biasing resistor from the supply rail — a higher value resistor saves quiescent power but must still deliver at least 700 µA to keep the reference in regulation. The ±0.5% tolerance means the reference voltage at 25°C stays within 2.483 V to 2.507 V — tighter than the standard ±1% or ±2% grades. For a 5 V output supply, that translates to about ±25 mV regulation error from the reference alone.","metaTitle":"TL432BIDBZR shunt voltage reference, ±0.5% tolerance","metaDescription":"Texas Instruments TL432BIDBZR adjustable shunt reference, ±0.5% 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); Cut Tape (CT)","Tolerance":"±0.5%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Active","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"100 mA","Current - Supply":"-","Current - Cathode":"700 µA","Base Product Number":"TL432","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"-40°C~85°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":"$0.5100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2e8567ad04842692d5fb8309c69e90b6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL432BIDBZR/alternatives.json"},"ai":{"faq":[{"question":"Can TL432BIDBZR replace TL431 in a SOT-23-3 footprint?","answer":"Yes — the TL432BIDBZR uses the same SOT-23-3 package and three-lead pinout as the TL431 in that package.
