Note:
The PIC16F72X devices have an internal low dropout voltage regulator. An external capacitor must be
connected to one of the available V
connected to one of the available V
CAP
pins to stabilize the regulator. For more information, see
Section 5.0 “Low Dropout (LDO) Voltage Regulator”. The PIC16LF72X devices do not have the voltage
regulator and therefore no external capacitor is required.
