Features & Applications

The TS431AIZ is a low-voltage, three-terminal, programmable shunt voltage reference. The output voltage can be set to any value between Vref (1.24 V) and 6 V with two external resistors.

The TS431 is able to operate at a lower voltage (1.24 V) and lower cathode current than the widely used TL431 and TL1431 shunt voltage reference. When driving an optocoupler, the TS431 is particularly useful for regulating 3.3 V switching power supplies.

Features:

  • Low voltage operation: 1.24 to 6 V
  • 2 %, 1 % and 0.5 % voltage precision
  • Wide operating range cathode current: 60 μA to 30 mA
  • Low output impedance: 0.2 Ω
  • Typically stable for any capacitive loads
  • ESD protection:
    • Human body model: 2 kV
    • Machine model: 200 V
  • 100 ppm/°C temperature coefficient
