TL431ACDR2 Description

Short technical summary and product information.

The TL431ACDR2 integrated circuit by ON Semiconductor is a three-terminal programmable shunt regulator diode. It functions as a low temperature coefficient zener, programmable from Vref up to 36V using two external resistors. This device exhibits a wide operating current range from 1.0 mA to 100 mA with a typical dynamic impedance of 0.22 Ω.

 

Key electrical characteristics include a programmable output voltage up to 36V and a typical temperature coefficient of 50 ppm/°C over its full operating range. The voltage reference tolerance is typically ±0.4% at 25°C. The device is designed for operation over a temperature range of 0°C to 70°C.

 

Packaged in an 8-pin SOIC surface mount configuration, the TL431ACDR2 is suitable for various applications. Its characteristics make it an excellent replacement for zener diodes in circuits such as digital voltmeters, power supplies, and op-amp circuitry. It can be used as either a positive or negative voltage reference.
