Table 5-2: Power Distribution Estimate (9VS to 220V Supplies)
Table 5-1 shows the Power Distribution for the 3.3V
through 9V supplies, and Table 5-2 for the 9VS to
220V supplies. The tables indicate the estimated
current, in Ma, supplied to the various circuits. When
there is more than one supply of the same value, a
superscript number is added to those supplies. For
instance, 3.3V
