DESCRIPTION

3
The L7800 series of three-terminal positive
regulators is available in TO-220 ISOWATT220
TO-3 and D2PAK packages and several fixed
output voltages, making it useful in a wide range
of applications.Theseregulators can provide local
on-card regulation, eliminating the distribution
problems associated with single point regulation.
Each type employs internal current limiting,
thermal shut-down and safe area protection,
making it essentially indestructible. If adequate
heat sinking is provided, they can deliver over 1A
output current. Although designed primarily as
fixed voltage regulators, these devices can be
used with external components to obtain
adjustablevoltages and currents.

Figure 33 : Protection against Input Short-circuit
with High Capacitance Loads.
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 to ground.
