  SO T2 TL431 family
  Adjustable precision shunt regulator
  Rev. 4 -- 30 June 2011 Product data sheet 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. 3 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.
