Voltage Regulator Specifications

The 56F8322/56F8122 have two on-chip regulators. One supplies the PLL and has no external pins;
therefore, it has no external characteristics which must be guaranteed (other than proper operation of the
device). The second regulator supplies approximately 2.6V to the device’s core logic. This regulator
requires two external 2.2

µ

F, or greater, capacitors for proper operation. Ceramic and tantalum capacitors

tend to provide better performance tolerances. The output voltage can be measured directly on the V

CAP

pins. The specifications for this regulator are shown in

Table 10-6
