12. Module: Guidelines for Getting Started
2.4
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
regulator, while tying it to ground disables the regulator.
Refer to Section 23.3.2 “On-Chip Voltage Regulator”
for details on connecting and using the on-chip regulator.
When the regulator is enabled, a low-ESR (< 5Ω)
capacitor is required on the V
stabilize the voltage regulator output voltage. The V
V
use a capacitor of 10 µF connected to ground. The type
can be ceramic or tantalum. Suitable examples of
capacitors are shown in
equivalent specification can be used.
Designers may use

It is recommended that the trace length not exceed
0.25 inch (6 mm). Refer to Section 26.0 “Electrical
Characteristics” for additional information.
When the regulator is disabled, the V
must be tied to a voltage supply at the V
Refer to Section 26.0 “Electrical Characteristics” for
information on V
Note that the “LF” versions of some low pin count
PIC18FJ parts (e.g., the PIC18LF45J10) do not have
the ENVREG pin. These devices are provided with the
voltage regulator permanently disabled; they must
always be provided with a supply voltage on the
V
