  transients 34 The architecture of linear regulators has remained virtually
  unchanged since the introduction of the 3-terminal floating
  voltage regulator in 1976. Architectures have settled on either the
  floating architecture (LT317) or an amplifier loop with feedback
  from the output to the amplifier. These architectures inherently
  limit regulator versatility, regulation and accuracy. In 2007, Linear
  Technology released the LTВ®3080, introducing a new linear regulator
  architecture that expanded versatility,
  significantly improved performance,
  and allowed easy parallel operation.
  The LT3081 is one of this new
  class of linear regulator, specifically
  featuring a wide safe operating
  area for industrial applications.

  feedback resistors set the output voltage and attenuate …
