Programmable Voltage Regulator - TL431
The TL431 is a programmable shunt regulator which can provide both positive and negative reference voltages. It is a Zener diode whose voltage rating can be adjusted based on the value of resistors connected to the reference pin. It is commonly used as a low cost reference voltage provider in isolated power supply circuits.
