For adjustable output voltage version only.
A feedforward capacitor, shown across R2 in Table 9-6, is used when the output voltage is greater than 10 V or when COUT has a very low ESR. This capacitor adds lead compensation to the feedback loop and increases the phase margin for better loop stability. For CFF selection, see the Section 184.108.40.206 section.
