a. The use of Tantalum capacitors is not recommended.
b. The peak to peak output ripple is measured at 20 MHz Bandwidth within the operational range.
When using the internal voltage regulator controllers built into the 82563EB/82564EB, series
resistors may need to be placed in series with the collector in order to prevent the PNP transistors
from overheating. These series resistors dissipate a portion of the power that would otherwise be
dissipated by the PNP devices. The value and power rating of the resistors must be carefully chosen
to balance thermal limits against the PNP characteristics against total current draw. The regulator
must never drop below the minimum V
