LinkMejor 5Pcs TL431A TO-92 Type Adjustable Precision Shunt Regulator 2.5-36V

The TL431 is three-terminal adjustable shunt regulators, with specified thermal stability over applicable automotive, commercial, and temperature ranges. The output voltage can be set to any value between Vref (approximately 2.5 V) and 36 V, with two external resistors. This devices have a typical output impedance of 0.2 ohm. Active output circuitry provides a very sharp turn-on characteristic, making these devices excellent replacements for Zener diodes in many applications, such as onboard regulation, adjustable power supplies, and switching power supplies.
