8.2.2.4 Transient Response

As with any regulator, increasing the size of the output capacitor reduces overshoot and undershoot magnitude but increase duration of the transient response. In the adjustable version, adding CFB between OUT and FB improves stability and transient response. The transient response of the TPS799-Q1 is enhanced by an active pulldown that engages when the output overshoots by approximately 5% or more when the device is enabled. When enabled, the pulldown device behaves like a 350-Ω resistor to ground.
