BoosterPack™ Development Kit (BOOSTXL-

CC3135)

2.4.2

Onboard LDO Power Supply

On some LaunchPad™ kits, the 3.3 V cannot source the 450-mA peak current needed for the BOOSTXL-
CC3135 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 BOOSTXL-CC3135 and LaunchPad kit in a shared-load manner
(see

Figure 6. 3.3-V Power from LDO
