26.2
All PIC24FJ256GB110 family 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 PIC24FJ256GB110 family
incorporate an on-chip regulator that allows the device
to run its core logic from V
The regulator is controlled by the ENVREG pin. Tying V
to the pin enables the regulator, which in turn, provides
power to the core from the other V

configurations.
26.2.1
When it is enabled, the on-chip regulator provides a
constant voltage of 2.5V nominal to the digital core
logic.
The regulator can provide this level from a V

order to prevent “brown out” conditions when the volt-
age drops too low for the regulator, the regulator enters
Tracking mode. In Tracking mode, the regulator output
follows V
When the device enters Tracking mode, it is no longer
possible to operate at full speed. To provide information
about when the device enters Tracking mode, the
on-chip regulator includes a simple, Low-Voltage
Detect circuit. When V

Interrupt Flag, LVDIF (IFS4<8>). This can be used to
generate an interrupt and put the application into a
low-power operational mode, or trigger an orderly
shutdown.
Low-Voltage Detection (LVD) is only available when the
regulator is enabled.
