... No input capacitor is needed if the regula- tor is within 6 inches of the power supply filter capacitor using 18 gauge stranded wire For longer wire runs the LM196 input should be bypassed locally with (or larger) solid tantalum capacitor or a 100 mF (or larger) alu- minum electrolytic capacitor ...
