Typical Application
Design Considerations
The KA79L05A fixed voltage-regulator is 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 cir-
cuit 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 ensure stable operation under all load conditions. A 0.33 μ F 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 regulator's input terminals. Good construction tech-
niques 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.

Figure 3. Typical Application
A common ground is required between the input and the output voltages. The input voltage must remain typically 2.0 V
above the output voltage, even during the low point on the input ripple voltage.
* C I is required if regulator is located an appreciable distance from power supply filter.
** C O improves stability and transient response.
