Inrush current at startup
Peak current drawn by LDO
from DV_CC
Time taken by LPM LDO (LDO
in LPM3, LPM4, or LPM3.5) to
get ready after a cold powerup
or LPM4.5, before it may be
enabled. ⁽¹⁾

(1) If LPM LDO is attempted to be enabled before this time, the active mode LDO automatically remains ON at the expense of system
power to allow the SOC operations to continue smoothly.
