PIC18F87K90 FAMILY
28.3
All of the PIC18F87K90 family devices power their core
digital logic at a nominal 3.3V. For designs that are
required to operate at a higher typical voltage, such as
5V, all family devices incorporate two on-chip regula-
tors that allows the device to run its core logic from
V
• Normal On-Chip Regulator
• Ultra Low-Power, On-Chip Regulator
The hardware configuration of these regulators are the
same and are explained in Section 28.3.1 . The regula-
tors’ only differences relate to when the device enters
Sleep, as explained in Section 28.3.2 .
28.3.1
The regulator can be enabled or disabled only by
hardware. The regulator is controlled by the ENVREG
pin and the V
28.3.1.1
Tying V
provides power to the core from the other V
When the regulator is enabled, a low-ESR filter capac-
itor must be connected to the V
Figure 28-2). This helps maintain the regulator’s
stability. The recommended value for the filter capacitor
is given in Section 31.2 DC Characteristics .
28.3.1.2
If ENVREG is tied to V
this case, a 0.1 F capacitor should be connected to
the V
When the regulator is being used, the overall voltage
budget is very tight. The regulator should operate the
device down to 1.8V. When V
regulator no longer regulates, but the output voltage fol-
lows the input until V
the output of the regulator output may drop to 0V.
