Integrated voltage regulator

Table 5.
An external 1.8 V regulator may replace both internal regulators. The STM32W108 can
control external regulators during deep sleep using open-drain GPIO PA7, as described in
Section 8: General-purpose
sleep to disable the external regulator and an external pull-up is required to release this
signal to indicate that supply voltage should be provided. Current consumption increases
approximately 2 mA when using an external regulator. When using an external regulator the
internal regulators should be disabled through software.
