That 2.5 V minimum is the internal bandgap — set the output higher with two resistors. ## Active lifecycle — no near-term LTB worry The ATL431LIAIDBZR carries an Active status and is ROHS3 compliant. ## SOT-23-3 footprint — drop-in for the TL431 The SOT-23-3 package (also listed as TO-236-3, SC-59) matches the industry-standard pinout for adjustable shunt references. The adjustable output means you keep the same resistor divider. The 100 µA minimum cathode current is lower than the 1 mA typical for many shunt references, which helps in low-power bias circuits.","metaTitle":"ATL431LIAIDBZR Shunt Voltage Reference, Adjustable 2.5V–36V","metaDescription":"TI ATL431LIAIDBZR adjustable shunt reference, ±1% tolerance, 2.5V to 36V output, -40°C to 85°C, SOT-23-3.
