typical soft start period (t SS ) at maximum output current (I OUT_MAX )
for several conditions.
A 20 nF soft start capacitor results in negligible input current
overshoot at startup and is therefore suitable for most applications.
However, if an unusually large output capacitor is used, a longer

ESR × C OUT
The capacitor (C2) is chosen to cancel the zero introduced by
output capacitance ESR. C2 is calculated using the following
equation:

For low ESR output capacitance such as with a ceramic capaci-
tor, C2 is optional. For optimal transient performance, the
R COMP and C COMP may need to be adjusted by observing the load
transient response of the ADP1610. For most applications, the
compensation resistor is to be in the range of 30 kΩ to 400 kΩ,
and the compensation capacitor is to be in the range of 100 pF
to 1.2 nF. Table 5 shows external component values for several
