LOW DROPOUT (LDO)
VOLTAGE REGULATOR
The PIC16F707 device 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 VDD and I/O pins to operate
at a higher voltage. There is no user enable/disable
control available for the LDO, it is always active. The
PIC16LF707 operates at a maximum VDD of 3.6V and
does not incorporate an LDO.
A device I/O pin may be configured as the LDO voltage
output, identified as the VCAP pin. Although not
required, an external low-ESR capacitor may be
connected to the VCAP pin for additional regulator
stability.
The VCAPEN<1:0> bits of Configuration Word 2
determines which pin is assigned as the VCAP pin.
Refer to Table 5-1.
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 Section 25.0 “Electrical
