L7800 SERIES POSITIVE VOLTAGE REGULATORS .. .. . OUTPUT CURRENT UP TO 1.5A OUTPUT VOLTAGES OF 5; 5.2; 6; 8; 8.5; 9; 12; 15; 18; 20; 24V THERMAL OVERLOAD PROTECTION SHORT CIRCUIT PROTECTION OUTPUT TRANSISTOR SOA PROTECTION DESCRIPTION The L7800 series of three-terminal positive regulator is available in TO-220, ISOWATT220 and TO-3 packages and with several fixed output voltages making it useful in a wide range of applications. These regulators 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 adjustable voltages and currents.

VO falls when the light goes up VO rises when the light goes up Figure 33 : Protection against Input Short-circuit with High Capacitance Loads. Applications with high capacitance loads and an output voltage greater than 6 volts need an external diode (see fig. 33) to protect the device against input short circuit. In this case the input voltage falls rapidly while the output voltage decreases showly. The capacitance discharges by means of the Base-Emitter junction of the series pass transistor in the regulator.
