Its ±0.5% initial tolerance suits precision bias and feedback circuits where a standard 1% or 2% part would shift the output beyond the design window. ## Output current and cathode current limits Minimum cathode current for regulation is 600 µA — below that threshold the reference output may drift, so the external resistor from cathode to the supply rail must be sized to keep at least 600 µA flowing through the device at all load conditions.","metaTitle":"TI TL431BCDBVT Shunt Reference, ±0.5% Tolerance, SOT-23-5","metaDescription":"Texas Instruments TL431BCDBVT adjustable shunt voltage reference, ±0.5% tolerance, 100 mA output, SOT-23-5.
