Note:
(1) To specify an output voltage, substitute voltage value for "XX "
(2) Required for stability. For value given, capacitor must be solid tantalum. If aluminium electronics are used, at least ten times
value shown should be selected. CI is required if regulator is located an appreciable distance from power supply filter.
(3) 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.
