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 ...

(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.

[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 ...

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 ...
