TL431 Constant Current Source
a low noise phono preamp using 4 TL431 - diyAudio
The TL431 behaves like a regulated Z diode, with a additional transistor it can supply more current. With X1 and X2 the output voltage can be set.
TL431 high current shunt : r/AskElectronics - Reddit
When the TL431 shunts itself, the base of the PNP is at a lower potential because of the unmarked resistor connecting it to the supply voltage.
