The TL431C is a three-terminal programmable shunt regulator diode from N-A. It functions as a low temperature coefficient zener, with an output voltage programmable from Vref (approximately 2.5V) up to 36V using two external resistors. This device exhibits a wide operating current range of 1.0 mA to 100 mA and a typical dynamic impedance of 0.22 Ω.
Key electrical characteristics include a voltage reference tolerance of ±0.4% typical at 25°C (for the TL431B series) and an equivalent full-range temperature coefficient of 50 ppm/°C typical. The device is temperature compensated for operation over its full rated operating temperature range.
Designed for various applications, the TL431C is suitable as a replacement for zener diodes in digital voltmeters, power supplies, and op-amp circuitry. Its 2.5V reference is convenient for obtaining a stable reference from 5.0V logic supplies. It can be used as either a positive or negative voltage reference due to its shunt regulator operation.
The TL431C is available in a TO-92 package, suitable for through-hole mounting.
