9. See Figure 1-2. R_L and C_L reflect the recommended minimum resistance and maximum capacitance
required for the internal op-amp's stability and signal integrity. In this circuit topology, C_L will effectively
move the dominant pole of the two-pole amp in the output stage. Increasing this value beyond the
recommended 100 pF can cause the internal op-amp to become unstable.
