link to page 14 link to page 13 Low Voltage Precision Adjustable Shunt Regulator TLV431, NCV431, SCV431 The TLV431A, B and C series are precision low voltage shunt regulators that are programmable over a wide voltage range of 1.24 V to 16 V. The TLV431A series features a guaranteed reference accuracy of ±1.0% at 25°C and ±2.0% over the entire industrial temperature range of

−40°C to 85°C. The TLV431B series features higher reference accuracy of ±0.5% and ±1.0% respectively. For the TLV431C series, the accuracy is even higher. It is ±0.2% and ±1.0% respectively. These devices exhibit a sharp low current turn−on characteristic with a low dynamic impedance of 0.20 W over an operating current range of 100 mA to 20 mA. This combination of features makes this series an excellent replacement for Pin 1. Reference zener diodes in numerous applications circuits that require a precise 2. Anode reference voltage. When combined with an optocoupler, the 1 1 3. Cathode 2 2 TLV431A/B/C can be used as an error amplifier for controlling the 3 3 feedback loop in isolated low output voltage (3.0 V to 3.3 V) switching STRAIGHT LEAD BENT LEAD BULK PACK TAPE & REEL power supplies. These devices are available in economical TO−92−3 and AMMO PACK micro size TSOP−5 and SOT−23−3 packages.
