  DESIGN FEATURES High Voltage Micropower Regulators
  Thrive in Harsh Environments by Todd Owen
  Introduction
  Some of the harshest environments
  for electronic circuits are found in
  industrial and automotive applications, where high, unpredictable input
  voltage transients, failing batteries and
  disconnected supplies are an expected
  part of doing business. A 12V car battery and a 48V industrial supply rail
  offer many of the same power supply
  design challenges. Input voltages can
  spike to 75V on an industrial rail or
  60V during an automotive load dump.
  Cold cranking or overloaded lines can
  drop the supply voltage to only a few
  volts. Through all of this, the power
  supply must be kept alive and remain
  in regulation for critical circuitry, and
  it cannot dissipate much quiescent
  power—dead car batteries or lost industrial sensor data do not make for
  happy customers. Tough New Regulators
  Provide Flexibility in
  Rough Environments Three new linear regulators provide …
