11. Voltage regulators may be designed with a minimum equivalent internal resistance to ensure that the output
voltage, at maximum current output, is no greater than the nominal (i.e., typical) voltage level of V
CCCORE
(V
CCCORE_TYP
). In this case, the maximum current level for the regulator, Icc
CORE_REG
, can be reduced from
the specified maximum current Icc

12.The current specified is the current required for a single Pentium III processor. A similar amount of current is
drawn through the termination resistors on the opposite end of the AGTL+ bus, unless single-ended
