TS431:Low voltage adjustable shunt reference

The TS431 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 using 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 suitable for regulating 3.3 V switching power supplies.

Key Features

  • Low voltage operation: 1.24 to 6 V

  • Typically stable for any capacitive loads
  • ESD protection:
    • Human body model: 2 kV
    • Machine model: 200 V
  • 100 ppm/°C temperature coefficient
  • Automotive grade version available
