Product overview

Description

The TS431 is a low-voltage, three-terminal, adjustable 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.

  • All features

    • AEC-Q100 qualified (SOT23-5)
    • 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
    • Automotive grade version available
