The on-chip voltage regulator enable pin, ENVREG,
must always be connected directly to either a supply
voltage or to ground. Tying ENVREG to V
the regulator, while tying it to ground disables the
regulator. Refer to

When the regulator is enabled, a low-ESR (< 5Ω)
capacitor is required on the V

V
must use a capacitor of 10 µF connected to ground. The
type can be ceramic or tantalum. Suitable examples of
capacitors are shown in
equivalent specifications can be used.

It is recommended that the trace length not exceed
0.25 inch (6 mm). Refer to

PIC18F87K90 FAMILY
Some PIC18FXXKXX families, or some devices within
a family, do not provide the option of enabling or
disabling the on-chip voltage regulator:
