TABLE 23-2:
23.2
All of the dsPIC33F devices power their core digital
logic at a nominal 2.5V. This may create an issue for
designs that are required to operate at a higher typical
voltage, such as 3.3V. To simplify system design, all
devices in the dsPIC33F family incorporate an on-chip
regulator that allows the device to run its core logic from
V
The regulator provides power to the core from the other
V
(less than 5 ohms) capacitor (such as tantalum or
ceramic) must be connected to the V
(Figure 23-1). This helps to maintain the stability of the
regulator. The recommended value for the filter capac-
itor is provided in
TABLE 26-12: “Internal Voltage Regulator Specifi-
cations” located in Section 26.1 “DC Characteris-
tics”.
