Tl431 Application Note. The output voltage can. The tl431 is attributed with the following main features.
Q1 2009 issue analog applications journal. Description the tl431 is a three terminal adjustable shunt regulator with specified thermal stability over applicable temperature v ref 2 495v and v with40 two external resistors. The tl431 programmable zener the tl431 is the most popular choice in nowadays designs it associates an open collector op amp and a reference voltage the internal circuitry is self supplied from the cathode current when the r node exceeds 2 5 v it sinks current from its cathode 2 5v k a r tl431a k a r r a k the tl431 is a shunt regulator.
