4. See Figures 1 and 2 on page 16. R_L and C_L reflect the minimum resistance and maximum capacitance
allowed in order to maintain stability in the internal op-amp. C_L affects the dominant pole of the internal
output amp; increasing C_L beyond 100 pF can cause the internal op-amp to become unstable.
