Tl431 Schaltung. These monolithic ic voltage references operate as a low temperature coefficient zener which is programmable from v ref to 36 v with two external resistors. In addition low output drift versus.
Both the tl431 and tl432 devices are offered in three grades with initial tolerances at 25 c of 0 5 1 and 2 for the b a and standard grade respectively. The output voltage can be dimensioned using just two resistors across the specified pin outs of the device. The tl431 a b integrated circuits are three terminal programmable shunt regulator diodes.

These monolithic ic voltage references operate as a low temperature coefficient zener which is programmable from vref to 36 v with two external resistors. It is a zener diode whose voltage rating can be adjusted based on the value of resistors connected to the reference pin. In addition low output drift versus.
