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.
