L78Sxx L78SxxC
2 A positive voltage regulators
Features

Output current to 2 A Output voltages of 5; 7.5; 9; 10; 12; 15; 18; 24 V Thermal overload protection Short circuit protection Output transition SOA protection
Description
The L78Sxx series of three-terminal positive regulators is available in TO-220 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 shutdown and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 2 A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.

Figure 37. Protection against input short-circuit with high capacitance loads
1. Application with high capacitance loads and an output voltage greater than 6 volts need an external diode (see Figure 30 on page 22) to protect 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 the BaseEmitter 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.
