  DESIGN FEATURES Very Low Dropout (VLDO) Linear
  Regulator Outperforms Switching
  Regulators in Low VOUT Applications by Anthony Bonte Introduction
  Each new generation of computing
  systems demands more power, lower
  operating voltages and more supply
  voltages. CPU core, logic and termination voltages below 1.8V are common.
  Three or more supply voltages are the
  norm, where a high efficiency synchronous switching regulator typically
  generates each voltage. These systems
  have stringent output voltage regulation specifications for input voltage
  change, output load current change,
  temperature change and output load
  step response. These requirements
  mandate the need for an accurate,
  high-speed regulator. In applications
  that draw 1A–10A of output current, a
  VLDOв„ў linear regulator that operates
  from a low VIN has several advantages
  over a switching regulator. A VLDO
  consumes less board space, requires
  fewer components and costs less than
  a switcher solution. When the inputto-output voltage differential is low, …
