Internal and external references
It is possible to set two internal references, 0.6 V and 1.2 V, or provide an external reference
from 0 V to 2.5 V. The maximum value of the external reference depends on the V
V
maximum external reference is 2.5 V (typ).

Providing an external reference from 0V to 450 mV the output voltage will be regulated but
some restrictions must be considered:

To set the resistor divider it must be considered that a 100 kΩ pull-down resistor is
integrated into the device (see
voltage at the EAREF pin is captured by the device at the start-up when Vcc is about 4 V.
