For the adjustable-voltage version device, a feed-forward capacitor (C_FF) can be connected from the OUT pin to the FB pin. C_FF improves transient, noise, and PSRR performance, but is not required for regulator stability. Recommended C_FF values are listed in the Section 6.3 table. A higher capacitance C_FF can be used; however, the start-up time increases. For a detailed description of C_FF tradeoffs, see the Pros and Cons of Using a Feedforward Capacitor with a Low-Dropout Regulator application report.
