It delivers up to 100 mA output current while the cathode current requirement is just 1 mA — typical for biasing the reference in a flyback converter's secondary-side feedback loop or as a precision comparator threshold. ## Through-hole 8-DIP — legacy board fit Housed in an 8-DIP (0.300\", 7.62 mm) through-hole package, also designated 8-PDIP, the TL431IP suits prototype builds, rework-friendly layouts, and applications where through-hole assembly is preferred over surface-mount.","metaTitle":"TL431IP Adjustable Shunt Reference, ±2.2%, 8-DIP, Obsolete","metaDescription":"TL431IP adjustable shunt voltage reference, 2.495 V min / 36 V max output, ±2.2% tolerance, 100 mA output, 8-DIP through hole.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tube","Tolerance":"±2.2%","Output Type":"Adjustable","Mounting Type":"Through Hole","Package / Case":"8-DIP (0.300\\\", 7.62mm)","Product Status":"Last Time Buy","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"100 mA","Current - Supply":"-","Current - Cathode":"1 mA","Base Product Number":"TL431","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"-40°C~85°C(TA)","Voltage - Output (Max)":"36 V","Supplier Device Package":"8-PDIP","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"2.495V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2e8567ad04842692d5fb8309c69e90b6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL431IP/alternatives.json"},"ai":{"faq":[{"question":"Is the TL431IP obsolete?","answer":"Yes, the TL431IP is listed as Obsolete.
