  40V Input, 3.5A Silent Switcher ВµModule Regulator for Automotive
  and Industrial Applications

  Introduction
  The LTMВ®8003 is a wide input and output range stepdown ВµModuleВ® regulator featuring the Silent SwitcherВ®
  architecture. Inputs from 3.4V to 40V can produce outputs
  from 0.97V to 18V, eliminating the need for intermediate
  regulation from batteries or industrial supplies. The pinout
  is specifically designed to be FMEA compliant, so the output
  stays at or below the regulation voltage during adjacent
  pin shorts, single pin shorts to ground or pins left floating.
  Redundant pins enhance electrical connections in the event
  a solder joint weakens or opens due to vibration, aging or
  wide temperature variations, such as in automotive and
  transportation applications.
  A complete solution fits a compact space not much larger
  than the 6.25mm Г— 9mm footprint of the LTM8003,
  including the input and output capacitors. The quiescent
  current of typical 25ВµA, and wide temperature operation from
  –40°C to 150°C (H-Grade) make it ideal for applications in
  automotive, transportation and industrial, where space is
  tight, the operational environment is harsh, and low quiescent …
