The TL431B is a three-terminal adjustable shunt regulator from Texas Instruments, designed for stable operation across various temperature ranges. It allows the output voltage to be set anywhere between approximately 2.5V and 36V using two external resistors.
Key electrical specifications include a minimum output voltage of 2.5V and a maximum output voltage of 36V. The device can sink a current capability from 1mA up to 100mA, with a typical output impedance of 0.2Ω. The B grade offers a reference voltage tolerance of 0.5% at 25°C.
This shunt regulator operates within a temperature range of -40°C to 125°C. It is available in a SOT-89 package, suitable for surface mounting (SMD/SMT).
The TL431B is an excellent replacement for Zener diodes in applications such as onboard regulation, adjustable power supplies, and switching power supplies.
