8.2.1 Voltage Regulator Specifications
The regulator supplies approximately 1.2 V to the MC56F84xxx’s core logic. This
regulator requires an external 2.2 µF capacitor on each VCAP pin for proper operation.
Ceramic and tantalum capacitors tend to provide better performance tolerances. The
output voltage can be measured directly on the VCAP pin. The specifications for this
regulator are shown in Table 16.
