Current Consumption
This section provides information on typical and maximum power consumption under various
conditions. Unless otherwise indicated, current consumption numbers include use of the on-chip
LDO regulator and therefore include I_DDC.
Nominal Power Consumption
The following table provides nominal figures for current consumption.
