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