The reference is adjustable from a minimum of 1.24V up to 6V, set by two external resistors, with a guaranteed tolerance of ±1% over the full -40°C to 125°C operating range. ## Where it fits in a BOM — shunt topology and the cathode current budget The TLV431 regulates by sinking current through its cathode to ground. The cathode current must stay above 100 µA to maintain regulation and must not exceed 15 mA. The ±1% tolerance holds over temperature. ## Lifecycle and sourcing — no LTB clock ticking The ROHS3 compliance is also confirmed — no conflict with EU or China RoHS directives for the production run. ## Packaging and marking — what to verify on incoming inspection This package is compatible with standard SOT-23-5 footprints, simplifying PCB layout for automotive designs.","metaTitle":"TLV431AQDBVRQ1 Automotive Shunt Voltage Reference","metaDescription":"TI TLV431AQDBVRQ1 adjustable shunt voltage reference, AEC-Q100 qualified, ±1% tolerance, 1.24V to 6V output, -40°C to 125°C, SOT-23-5.
