4.6 Higher VDDA loads or higher ambient temperatures
If it is necessary to supply higher currents to external 3.3V loads or if high ambient temperatures
>105°C are requested, it is possible to connect to the RTG pin an external load transistor. This external load
transistor provides a higher current for possible external devices and also decreases the internal power
dissipation.

4.7 Use of external resonator
It is possible to use an external resonator in case a higher precision of the frequency is requested.
