Adjustable precision shunt regulator
Rev. 5 — 01 September 2015
Product data sheet
1. Product profile
1.1 General description
Three-terminal shunt regulator family with an output voltage range between Vref and 36 V,
to be set by two external resistors.
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, for example, for Switch Mode Power
Supply (SMPS) applications.
The TL431xSDT types are designed for standard requirements and linear
applications.
