The L7800 series of three-terminal positive
regulators is available in TO-220, TO-220FP,
TO-220FM, TO-3 and D
2
PAK packages and
several fixed output voltages, making it useful in a
wide range of applications. These regulators c an
provide local on-card regulation, eliminating the
distribution problems associated w ith 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 us ed with ex ternal components to
obtain adjustable voltage and currents.

Figure 37: Protection against Input Short-Circuit with High Capacitance Loads
Applica tion with high ca pacitance loads and an outpu t vo l ta ge greater than 6 volts need an external di ode (see fig. 33) to pro tect the device
against input short circuit. In this case the input voltage falls rapidly while the output voltage decrease slowly. The capacitance discharges by
means of th e Base-Emit ter junction of the series pass transistor in the re gul ator. If th e energy is sufficiently hi gh, the transi stor may be d estroyed. The external diode by -passes the current from the IC to ground.
