Internal Short Circuit Protection limits the maximum current the circuit will pass. In many low current applications, compensation ca- pacitors are not required. However, it is recom- mended 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 capaci- tor 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 ca- pacitor should be mounted with the shortest possible leads directly across the regulators input terminals. Good construction techniques should be used to mini- mize ground loops and lead resistance drops since the regulator has no external sense lead. Bypassing the output is also recommended. Figure 1.

In order to minimize dissipation the APL78L05 is chosen in this application. Resistor R determines the current as follows : IO = + IB 5.0V R IB =3.8mA over line and load changes For example, a 100mA current source would require R to be a 50 Ω, 1/2W resistor and the output voltage compliance would be the input voltage less 7V.
