It sits flat on the board with no heatsink pad — the 15 mA maximum output current is the practical limit before self-heating drifts the reference. That means TI is still manufacturing it, no last-time-buy notice has been issued, and it's safe to qualify into a new design or a production BOM. ROHS3 compliant, so no exemption expiry to track.","metaTitle":"TL431LIBCDBZR Shunt Voltage Reference","metaDescription":"TL431LIBCDBZR adjustable shunt reference, ±0.5% tolerance, 2.495V to 36V output, SOT-23-3, 0°C to 70°C.
