8.0
The PIC16F193X 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
PIC16LF193X operates at a maximum V
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<1:0> bits of Configuration Word 2 deter-
mines 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
Characteristics Table in the applicable Electrical
Specifications Chapter.
