TL431 Adjustable Precision Zener Diode - SOT-23 SMD Package

The TL431 is a three-terminal adjustable precision shunt regulator, often used as a programmable Zener diode, provided here in a compact SOT-23 SMD package. It offers a stable voltage reference with an adjustable output voltage range from 2.5V to 36V. Unlike fixed Zener diodes, the TL431 allows precise setting of the output voltage through external resistors, making it highly versatile for use in power supply regulation, voltage monitoring, switching regulators, and other precision circuits.
