On-Board LDO Power Supply
On some LaunchPads, the 3.3 V is not capable of sourcing the 350-mA peak current needed for the
CC3100MODBOOST. In this case, the on-board 3.3-V LDO can be used (see
). This LDO is
sourced from the USB connector on the CC3100MODBOOST and the LaunchPad in a shared load
manner.
