Application information
Figure 28. Protection against input short-circuit with high capacitance loads
Note:
36/56
Application with high capacitance loads and an output voltage greater than 6 volts need an
external diode (see
this case the input voltage falls rapidly while the output voltage decrease slowly. The
capacitance discharges by means of the base-emitter junction of the series pass transistor
in the regulator. If the energy is sufficiently high, the transistor may be destroyed. The
external diode by-passes the current from the IC to ground.
