TLV431, NCV431, SCV431 Low Voltage Precision Adjustable Shunt Regulator 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 25C and 2.0% over the entire industrial temperature range of -40C to 85C. 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 zener diodes in numerous applications circuits that require a precise reference voltage. When combined with an optocoupler, the TLV431A/B/C can be used as an error amplifier for controlling the feedback loop in isolated low output voltage (3.0 V to 3.3 V) switching power supplies. These devices are available in economical TO-92-3 and micro size TSOP-5 and SOT-23-3 packages.

Isolated Output Line Powered Switching Power Supply The above circuit shows the TLV431A/B/C as a compensated amplifier controlling the feedback loop of an isolated output line powered switching regulator. The output voltage is programmed to 3.3 V by the resistors values selected for R1 and R2. The minimum output voltage that can be programmed with this circuit is 2.64 V, and is limited by the sum of the reference voltage (1.24 V) and the forward drop of the optocoupler light emitting diode (1.4 V).
