  The Harsh Reality of Wide-Ranging 4V–36V Automotive
  Batteries Is No Problem for Triple Output Regulator in
  4mmВ Г—В 5mm QFN
  Michael Nootbaar DC/DC converters for automotive applications must operate
  in an environment of extremes. Input transients can exceed
  the nominal battery voltage by a factor of five and last
  hundreds of milliseconds, while temperatures under the
  hood soar far above the capability of typical commercial
  grade ICs. In this harsh environment, space is tight, so even
  the most robust devices must perform multiple functions.
  The LT3694/LT3694-1 meets these requirements by combining a 2.6A switching
  regulator and two low dropout linear
  regulators in a compact 4mmВ Г—В 5mm
  QFN package or a thermally enhanced
  TSSOP. The switching regulator requires
  a single inductor and has an internal
  power switch, cycle-by-cycle current
  limiting and track/soft-start control. Each
  LDO requires only an external NPN pass
  transistor and includes foldback current limiting and track/soft-start control. An internal overvoltage detector
  shuts off the switching regulator when
  VIN exceeds 38V, protecting the switch and
  the Schottky rectifier. This allows it to …
