DESCRIPTION
The TL431 and TL431A are 3-terminal adjustable shunt
regulators with specified thermal stability over applicable automotive and commercial temperature ranges.
The output voltage may be set to any value between VREF (approximately 2.
5V) and 36V with two external resistors (see Figure 4).
These devices have a typical output impedance of 0.
2Ω.
Active output circuitry provides a very sharp turn-on ch...
