APPLICATIONS INFORMATION
Design Considerations
The MC79L00, A Series of fixed voltage regulators are
designed with Thermal Overload Protections 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
length, 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
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. Normally 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.

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 ripple voltage.
* CI is required if regulator is located an appreciable
*
distance from the power supply filter
** CO improves stability and transient response.
