5.0 LOW DROPOUT (LDO)
VOLTAGE REGULATOR
The PIC16F720/721 devices differ from the
PIC16LF720/721 devices due to an internal Low
Dropout (LDO) voltage regulator. The PIC16F720/721
contain an internal LDO, while the PIC16LF720/721 do
not.
The lithography of the die allows a maximum operating
voltage of 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 3.2V, while I/O’s operate at 5.0V (VDD).
