*Required if regulator is separated from filter capacitor by more than 3 . For
value given, capacitor must be solid tantalum. 25 μF aluminum electrolytic
may be substituted.
†Required for stability. For value given, capacitor must be solid tantalum. 25
μF aluminum electrolytic may be substituted. Values given may be increased
without limit.
For output capacitance in excess of 100 μF, a high current diode from input
to output (1N4001, etc.) will protect the regulator from momentary input
shorts.
