To specify an output voltage, substitute voltage value
Required for stability. For value given, capacitor
must be solid tantalum. If aluminum electronics are
used, at least ten times value shown should be
selected. C
I
is required if regulator is located an
appreciable
distance from power supply filter.
To improve transient response. If
large capacitors
are used, a high current diode from input to output
(1N400l or similar) should be introduced to protect
the device from momentary input short circuit.
