The TL431BIDBZR,215 is a shunt voltage reference IC adjustable 2.495V 36 VV ±0.5% 100 mA TO-236AB manufactured by Nexperia. It is a three-terminal adjustable shunt regulator with an output voltage that is regulated to a precise value. This IC allows the user to program the output voltage with two external resistors, allowing it to be set within a ±0.5% accuracy range. The output is capable of sustaining up to 100 mA over a 36 VV voltage range making it suitable for a variety of applications. The device is housed in a TO-236AB package, providing a space efficient design for PCB circuit designs.
