#   This file holds all of the components involved with
#   DCDC 4  Linear Regulator  on the Hub Module.
#
#   This is a  3 Amp  LT1764  Linear Regulator for the  MGT_AVAUX  bus.
#
#   This is a  non-relatively_positioned_component_set  version of DCDC-4.
#
#   The DCDC4 supply has it own private version
#   of the LT1764A geometry.
