8.0
The PIC16F1946/47 has an internal Low Dropout
Regulator (LDO) which provides operation above 3.6V.
The LDO regulates a voltage for the internal device
logic while permitting the V
at a higher voltage. There is no user enable/disable
control available for the LDO, it is always active. The
PIC16LF1946/47 operates at a maximum V
and does not incorporate an LDO.
A device I/O pin may be configured as the LDO voltage
output, identified as the V
required, an external low-ESR capacitor may be con-
nected to the V
The VCAPEN bit of Configuration Word 2 determines
which pin is assigned as the V

On power-up, the external capacitor will load 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 on recommended capacitor values and the
constant current rate, refer to the LDO Regulator
