Rev. 3 — 5 November 2010
The TL431xDBZR types feature an enhanced stability area with a very low
load capacity requirement.
The TL431xFDT types offer an enhanced stability area and a higher
ElectroMagnetic Interference (EMI) ruggedness, e.g. for Switch Mode Power
Supply (SMPS) applications.
The TL431xSDT types are designed for standard requirements and linear
applications.
