PRODUCTION DATA.
Although a feed-forward capacitor (CFF) from the FB pin to the OUT pin is not required to achieve stability, a
10-nF external feed-forward capacitor optimizes the transient, noise, and PSRR performance. A higher capacitance CFF can be used; however, the start-up time is longer and the power-good signal can incorrectly indicate that the output voltage is settled. For a detailed description, see Pros and Cons of Using a Feed-Forward Capacitor with a Low Dropout Regulator.
