ALDO3 is used as the power supply for the LRADC keys voltage divider, in addition to supplying AVCC and VCC-PLL. While AVCC and VCC-PLL will accept any voltage between 2v7 and 3v3, LRADC needs a precise 3v0 input to maintain the expected 2:3 ratio between the internal 2v0 reference voltage and the external supply.
