4.5 PIC32MZ EC and PIC32MZ EF Power Requirements
Devices in the PIC32MZ EC and PIC32MZ EF families are also dual voltage supply designs like PIC32MX devices. However, the internal regulator does not require the external filter capacitor, and there is no corresponding VCAP or ENVREG pins. See Figure 4-4.
Refer to the AC/DC Characteristics and Timing Requirements and
the “Electrical Characteristics” chapter in the specific device data sheet for
the power requirements of the device.
