Tl431 is a controllable precision voltage regulator. Its output voltage can be arbitrarily set to any value from Vref (2.5V) to 36V with two resistors. The device's typical dynamic impedance is 0.2Ω, which is used in many applications to replace Zener diodes, such as digital voltmeters, op amp circuits, adjustable voltage supplies, switching power supplies, and more. Tl431 is produced by Texas Instruments, the so-called tl431 is a three-terminal adjustable shunt reference source with good thermal stability. Its output voltage can be arbitrarily set to any value digital voltmeter from Vref (2.5V) to 36V with two resistors, op amp circuit, adjustable voltage power supply, switching power supply and so on. Tl431 is a shunt regulator integrated circuit. Because of its good performance and low price, it is widely used in various power circuits. The package form is the same as that of the plastic triode 9013, as shown in FIG. Similar products have the double in-line shape shown in Figure b.
