The TL431 is a three-terminal programmable shunt regulator that implements Zener-like references with low temperature coefficients. Its output can be programmed from the internally set reference of ...

[Ken Shirriff] had to get down into a bit of semiconductor physics to give us an explanation of the TL431, which he calls “the most common chip you’ve never heard of”. [Ken] may well be ...

(Although we think he really made it for the fun of making it.) The circuit is centered around a TL431 programmable shunt regulator, which is an awesome and underrated chip in its own right.

The version of Multisim Spice offered by Analog Devices here does not include a device model for the TL431 group of voltage regulators, so when I needed one, I made one. Going for the super-simple and ...

The TL431 is a well-known voltage reference integrated circuit used in Switch-Mode Power Supply (SMPS) feedback loops. Combining a reference voltage and The TL431 is a well-known voltage reference ...
