Product Summary

The TL431IPK is a three-terminal adjustable shunt regulator with specified thermal stability over applicable automotive, commercial, and military temperature ranges. The TL431IPK is offered in three grades, with initial tolerances (at 25℃) of 0.5%, 1%, and 2%, for the B, A, and standard grade, respectively. In addition, low output drift vs temperature ensures good stability over the entire temperature range. The TL431IPK is characterized for operation from -40℃ to 85℃.
