Precision shunt reference with ±0.5% tolerance
The TLV431BIDCKT from Texas Instruments is an adjustable shunt voltage reference that delivers a tighter ±0.5% initial tolerance compared to the standard TLV431's 1% grade. It regulates from a minimum of 1.24 V up to 6 V, sinking up to 15 mA with a cathode current floor of 100 µA.
Industrial temperature range, SC-70-6 footprint
The SC-70-6 (SOT-363) package is a 6-pin surface-mount footprint roughly 2.0 mm × 1.25 mm — smaller than an SOT-23-3, which helps when board space is tight. The adjustable output means the feedback divider sets the regulation point, so the same BOM line covers multiple output voltages with a resistor change.
The base product number TLV431 spans multiple tolerance grades and package options, giving the procurement team flexibility to dual-source within the family without requalifying the feedback network.
