The
PIC18LF1XK50 devices due to an internal Low
Dropout (LDO) voltage regulator. The PIC18F1XK50
contain an internal LDO, while the PIC18LF1XK50 do
not.
The lithography of the die allows a maximum operating
voltage of the nominal 3.6V on the internal digital logic.
In order to continue to support 5.0V designs, a LDO
voltage regulator is integrated on the die. The LDO
voltage regulator allows for the internal digital logic to
operate at 3.3V, while I/O’s operate at 5.0V (V
The LDO voltage regulator requires an external bypass
capacitor for stability. The V
an external bypass capacitor. It is recommended that
the capacitor be a ceramic cap between 0.22 to 0.47 µF.
On power-up, the external capacitor will look like a
large load on the LDO voltage regulator. To prevent
erroneous operation, the device is held in Reset while
a constant current source charges the external
capacitor. After the cap is fully charged, the device is
released from Reset. For more information, refer to
