1 Series 3-Terminal Positive Regulators Description The series of three terminal positive regulators is available with several fixed output voltages making them useful in a wide range of applications, When used as a zener diode/resistor combination replacement, the usually results in an effective output impedance improvement of two orders of magnitude, and lower quiescent current. These regulators can provide local on card regulation, eliminating the distribution problems associated with single point regulation. The voltages available allow the SN78lxx to be used in logic systems, instrumentation, HiFi, and other solid state electronic equipment..

8 Electronics Design Considerations The 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 Limits the maximum current the circuit will pass. In many low current applications, compensation capacitors are not required. However, it is recommended that the regulator input be bypassed with a capacitor if the regulator is connected to the power supply filter with long wire lengths, or if the output load capacitance is large. The 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. Good construction techniques should be used to minimize ground loops and lead resistance drops since the regulator has no external sense lead. Bypassing the output is also recommended. Regulator The regulators can also be used as a current source when connected as above. In order to minimize dissipation the SN78L05 is chosen in this application. Resistor R determines the current as follows: Iout = 5.0V R + I B I B =3.8mA over line and load changes For example, a 100mA current source would require R to be a 50Ω, 1/2 W resistor and the output voltage compliance would be the input voltage less 7V.
