USB PWR
Hardware Description
2.4.2
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
CC3100BOOST. In such a case, the on-board 3.3 V LDO can be used (see
). This LDO would be
sourced from the USB connector on the CC3100BOOST and the LaunchPad in a shared load manner.
