TL431 SMD SOIC-8 Integrated

TL431 and TL432 have established thermal stability within applicable automotive, commercial and military temperature ranges. They are adjustable shunt regulators with three terminals. The output voltage can be set to any value between Vref (approximately 2.5 V) and 36 V with two external resistors. These devices have a typical output impedance of 0.2 im. The active output circuitry turns the characteristics very sharply, making these devices an excellent alternative to Zener diodes in many applications such as embedded regulation, adjustable power supplies, and switching power supplies.
