3 Description
The TL431LI / TL432LI are pin-to-pin alternatives to TL431 / TL432. TL43x LI offers better stability, lower temperature drift (VI(dev)), and lower reference current (Iref) for improved system accuracy.
The TL431 and TL432 devices are three-terminal adjustable shunt regulators, with specified thermal stability over applicable automotive, mercial, and military temperature ranges. The output voltage can be set...
