The TLV431ACDBVTE4 is officially obsolete per Texas Instruments' lifecycle record.
Adjustable shunt reference — the output voltage range and tolerance
A two-terminal shunt reference, the TLV431ACDBVTE4 regulates a voltage set by two external resistors between 1.24V minimum and 6V maximum. The ±1% tolerance means the reference voltage at 25°C stays within 1.24V ± 12.4 mV — tight enough for precision biasing in 8-bit ADC references or comparator thresholds. Cathode current range is 80 µA to 15 mA; the minimum load ensures the shunt stays in regulation across the full output voltage range.
SOT-23-5 footprint and temperature grade
Supplied in a SC-74A / SOT-753 package, the SOT-23-5 footprint occupies minimal board area — about 2.9 mm × 1.6 mm — and suits compact PSU or sensor modules. Tape & Reel (TR) packaging — 3000 units per reel, standard for pick-and-place assembly.
