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, feed-forward capacitor improves the noise and PSRR performance. A higher capacitance CFF can be used; however, the startup time is longer and the power-good signal can incorrectly indicate that the output voltage has settled. For a detailed description, see the Pros and Cons of Using a Feedforward Capacitor with a Low-Dropout Regulator application report.
