Depending upon routing resistors and battery type, TI recommends adding two 100-µF ceramic capacitors to help provide the peak current drawn by the CC3220MODx and CC3220MODAx modules.
The module enters a brown-out condition whenever the input voltage dips below VBROWN (see Figure 8-4 and Figure 8-5). This condition must be considered during design of the power supply routing specifically if operating from a battery. For more details on brown-out consideration, see Section 8.7.
