The 15 mA ceiling limits how much external load the shunt can sink directly; for higher current, the reference drives a pass transistor. ## SC-74A / SOT-23-5 — footprint and field swap That is a five-pin small-outline transistor package — common footprint for shunt references. On a board, the pinout is standard for the TLV431 family: cathode, anode, reference, and NC. That is the commercial grade — fine for office equipment, appliances, and indoor power supplies. If the BOM calls for extended temperature, look at the TLV431A or TLV431B industrial-grade siblings.","metaTitle":"TLV431BCDBVTG4 Shunt Reference, ±0.5% Tolerance, SOT-23-5","metaDescription":"Texas Instruments TLV431BCDBVTG4 adjustable shunt voltage reference, ±0.5% tolerance, 15 mA output, 100 µA cathode current.
