KA79LXXA
Typical Application
Design Considerations
The KA79LXXA 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. 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. An input bypass capacitor should be selected to provide good high frequency
characteristics to insure stable operation under all load conditions. A 0.33µF or larger tantalum, mylar, or other capacitor hav-
ing low internal impedance at high frequencies should be chosen. The bypass capacitor should be mounted with the shortest
possible leads directly across the regulator's input terminals. Normally 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 recom-
mended.
I
Figure 1. Positive And Negative Regulator
Figure 2. Typical Application
A common ground is required between the input and the output voltages. The input voltage must remain typically 2.0V above
the output voltage even during the low point on the input ripple voltage.
* C is required if regulator is located an appreciable distance from power supply filter.
1
* C improves stability and transient response.
