The rise time is defined as the time it takes the output voltage to
rise from 10% to 90% of V
dent on the rise time of the internal charge pump.
For very large values of output capacitance, the RC time constant
(where C is the load capacitance (C
can become a factor in the rise time of the output voltage. Because
RDS
for RC is RDS
for the ADP197 although capacitors can be used to suppress noise
on the board.

The turn-off time is defined as the time it takes for the output
voltage to fall from 90% to 10% of V
is also dependent on the RC time constant of the output capacit-
ance and load resistance. Figure 31 shows the typical turn-off
