PIC24FJ64GA004 FAMILY
APPENDIX B:
B.1
Devices in the PIC24FJ64GA004 family include a num-
ber of core features to significantly reduce the applica-
tion’s power requirements. For truly power-sensitive
applications, it is possible to further reduce the
application’s power demands by taking advantage of
the device’s regulator architecture. These methods
help decrease power in two ways: by disabling the
internal voltage regulator to eliminate its power con-
sumption, and by reducing the voltage on V
lower the device’s dynamic current requirements.
Using these methods, it is possible to reduce Sleep
currents (I
refer
Table 27-6). For dynamic power consumption, the
reduction in V
regulator, to 2.0V can provide a power reduction of
about 30%.
When using a regulated power source or a battery with
a constant output voltage, it is possible to decrease
power consumption by disabling the regulator. In this
case (Figure B-1), a simple diode can be used to
reduce the voltage from 3V or greater to the 2V-2.5V
required for V
power supplies, such as Lithium Coin cells, which
maintain a constant voltage over the life of the battery.

A similar method can be used for non-regulated
sources (Figure B-2). In this case, it can be beneficial
to use a low quiescent current external voltage regula-
tor. Devices such as the MCP1700 consume only 1 A
to regulate to 2V or 2.5V, which is lower than the
current required to power the internal voltage regulator.
