... Considerable effort was expended to make these devices easy to use and to minimize the number of external compo- nents not necessary to bypass the output, although this Schematic Diagram © 1999 National Semiconductor Corporation DS007138 does improve transient response somewhat. Input bypass- ing is needed, however, if the regulator is located very far from the filter capacitor of the power supply ...
