Regulator example
Figure 7. Core voltage regulator controller external components preferred configuration
There are three options for the bypassing and compensation networks for the 1.2V regulator controller. The component values
in the following table are the same for all PMC network requirements.
Table 16, Table 17 and Table 18 show the required component values for the three different options.
