The ±2.2% initial tolerance is a standard commercial grade — adequate for closed-loop feedback in off-line flyback supplies, linear regulators, and isolated DC-DC converters where the loop gain absorbs the reference spread. For precision metrology or 12-bit ADC references, a tighter grade (0.5% or 1%) would be specified instead. ## Through-hole DIP-8 — legacy footprint, active lifecycle It remains a safe BOM line for sustaining production on through-hole boards and for MRO replacements in existing power-supply designs. The 8-DIP package (7.62 mm body width) mates with standard 0.100-inch pitch sockets or wave-solder through plated holes. Not rated for under-hood automotive ambient, but fine for most chassis-mount and indoor equipment. ## Cathode current and output voltage range The shunt regulator requires a minimum 1 mA cathode current to maintain regulation — below that the reference drifts out of spec. This covers the common 3.3 V, 5 V, 12 V, and 24 V rail regulation range used in most industrial power stages.","metaTitle":"TL431IPG4 Adjustable Shunt Reference, 2.495V, ±2.2%, 100 mA","metaDescription":"Texas Instruments TL431IPG4 adjustable shunt voltage reference. 2.495 V min output, 100 mA cathode current, ±2.2% tolerance. 8-DIP through-hole, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","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)","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":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2e8567ad04842692d5fb8309c69e90b6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL431IPG4/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to TL431IPG4 in this component family?","answer":"The TL431IPG4 is the through-hole DIP-8 variant of the industry-standard TL431 adjustable shunt reference.
