That half-percent precision is the B-grade differentiator — it holds tighter than the standard 1% grade, which matters when the reference sets the ADC threshold or the regulation point in a power supply. ## Output current and temperature range The shunt can sink up to 15 mA continuous — enough to drive an optocoupler LED, bias a transistor, or pull up a resistor divider in a feedback loop.","metaTitle":"TLV431BCDBZT shunt reference, ±0.5% tolerance, SOT-23-3","metaDescription":"TLV431BCDBZT adjustable shunt voltage reference, ±0.5% tolerance, 15 mA output, SOT-23-3 package.
