6.3.5 Transient Response

As with any regulator, increasing the size of the output capacitor reduces overshoot and undershoot magnitude but increases the transient response duration. In the adjustable version, adding CFF between the OUT and FB pins improves stability and transient response performance. The transient response of the TPS735 device is enhanced by an active pulldown that engages when the output overshoots by approximately 5% or more when the device is enabled. The pull-down device operates like a 400-Ω resistor to ground when enabled.
