Protectionagainst Input Short-circuit
with High CapacitanceLoads.
Application with high capacitance loads and an output voltage
greater than 6 volts need an external diode (see fig. 33) to protect
the deviceagainst input short circuit. In this case the input voltage
falls rapidly while the output voltage decrease slowly. The
capacitance dischrges by means of the Base-Emitter junction of
the series pass transistor in the regulator. If the energy is
sufficently high, the transistor may be destroyed. The external
diode by-passes the current from the IC toground.
