Notes:
14. To specify an output voltage, substitute voltage value for "XX".
15. C I is required if the regulator is located an appreciable distance from the power supply filter. For value given,
capacitor must be solid tantalum. If aluminium electronics are used, at least ten times the value shown should be
selected.
16. C O improves stability and transient response. If large capacitors are used, a high-current diode from input to
output (1N4001 or similar) should be introduced to protect the device from momentary input short circuit.
