The Texas Instruments TL431AC is a three-terminal adjustable shunt regulator designed for specified thermal stability over automotive, commercial, and military temperature ranges. Its output voltage can be precisely set between approximately 2.5 V and 36 V using two external resistors.
Key features include a reference voltage tolerance of 1% at 25°C for the A grade, a typical output impedance of 0.2 Ω, and a sink-current capability ranging from 1 mA to 100 mA. The device operates from -40°C to 125°C, making it suitable for demanding environments.
With active output circuitry providing a sharp turn-on characteristic, the TL431AC serves as an excellent replacement for Zener diodes in applications such as onboard regulation, adjustable power supplies, and switching power supplies. It is also used for adjustable voltage and current referencing, secondary side regulation in flyback SMPSs, voltage monitoring, and as a comparator with an integrated reference.
The TL431AC is available in a SOT-23-3 package, suitable for surface mount applications.
