... Like any low-dropout regulator, the external capacitors used with the RT9014/A must be carefully selected for regulator stability and performance. Using a capacitor whose value is > 1μF on the RT9014/A input and the amount of capacitance can be increased without limit. The input capacitor must be located a distance of not more than 0.5 inch from the input pin of the IC and returned to a clean analog ground ...
