Typical Applications
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
(3) To improve transient response. If large capacitors are used, a high current diode from input to output (1N400l or similar)
value shown should be selected. C
should be introduced to protect the device from momentary input short circuit.
