The TS431AI is a three-terminal programmable shunt regulator diode manufactured by ST. This monolithic IC voltage reference functions as a low temperature coefficient zener, programmable from Vref up to 36 volts using two external resistors. It features a precision reference voltage of 2.495V with a ±1% tolerance for the AI variant.
The device operates over a wide current range of 1.0 to 100mA with a low dynamic output impedance of 0.2Ω. Its characteristics make it suitable as a replacement for zener diodes in applications such as digital voltmeters, power supplies, and op-amp circuitry. The TS431AI can be used as either a positive or negative stage reference due to its shunt regulator operation.
Key features include a fast turn-on response and an equivalent full-range temperature coefficient of 50ppm/°C. The TS431AI is designed for surface mount applications.
The TS431AI has a precision reference voltage of 2.495V with a ±1% tolerance.
The output voltage is programmable up to 36V.
The sink current capability ranges from 1mA to 100mA.
The typical dynamic output impedance is 0.2Ω.
The equivalent full-range temperature coefficient is 50ppm/°C.
