Onboard LDO Power Supply
On some LaunchPad kits, the 3.3 V cannot source the 350-mA peak current needed for the
CC3120BOOST board. In such a case, the onboard 3.3-V LDO can be used (see
). This LDO
would be sourced from the USB connector on the CC3120BOOST and LaunchPad kit in a shared-load
manner (see
).
