Description  
The L78xx series of three-terminal positive  
regulators is available in TO-220, TO-220FP, TO-  
3, D²PAK and DPAK packages and 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 1 A output  
current. Although designed primarily as fixed  
voltage regulators, these devices can be used  
with external components to obtain adjustable  
voltage and currents.

6.1  
Design consideration  
The L78xx Series of fixed voltage regulators are designed with thermal overload protection  
that shuts down the circuit when subjected to an excessive power overload condition,  
internal short-circuit protection that limits the maximum current the circuit will pass, and  
output transistor safe-area compensation that reduces the output short-circuit current as the  
voltage across the pass transistor is increased. In many low current applications,  
compensation capacitors are not required. However, it is recommended that the regulator  
input be bypassed with capacitor if the regulator is connected to the power supply filter with  
long lengths, or if the output load capacitance is large. An input bypass capacitor should be  
selected to provide good high frequency characteristics to insure stable operation under all  
load conditions. A 0.33 µF or larger tantalum, mylar or other capacitor having low internal  
impedance at high frequencies should be chosen. The bypass capacitor should be mounted  
with the shortest possible leads directly across the regulators input terminals. Normally  
good construction techniques should be used to minimize ground loops and lead resistance  
drops since the regulator has no external sense lead.  
The addition of an operational amplifier allows adjustment to higher or intermediate values  
while retaining regulation characteristics. The minimum voltage obtained with the  
arrangement is 2 V greater than the regulator voltage.  
The circuit of Figure 13 can be modified to provide supply protection against short circuit by  
adding a short circuit sense resistor, RSC, and an additional PNP transistor. The current  
sensing PNP must be able to handle the short circuit current of the three terminal regulator  
Therefore a four ampere plastic power transistor is specified.  
Figure 8.  
Fixed output regulator  
1. To specify an output voltage, substitute voltage value for "XX".  
2. Although no output capacitor is need for stability, it does improve transient response.  
3. Required if regulator is locate an appreciable distance from power supply filter.

Figure 28. Protection against input short-circuit with high capacitance loads  
Note:  
Application with high capacitance loads and an output voltage greater than 6 volts need an  
external diode (see Figure 23 on page 34) 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 base-emitter 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.
