TL431 ? Programmable Reference Voltage
RWF 500
TL431 is a regulator diode whose output voltage can be programmed by changing the value of resistors connected to it.
Product Description
It acts almost like a Zener diode except for that the voltage rating of this IC is programmable. It is commonly used to provide negative or positive voltage references.
