100 mA Negative Voltage
Regulators
THREE–TERMINAL LOW
CURRENT NEGATIVE FIXED
VOLTAGE REGULATORS
The MC79L00, A Series negative voltage regulators are
inexpensive, easy–to–use devices suitable for numerous applications
requiring up to100 mA. Like the higher powered MC7900 Series
negative regulators, this series features thermal shutdown and current
limiting, making them remarkably rugged. In most applications, no
external components are required for operation.
SEMICONDUCTOR
TECHNICAL DATA
The MC79L00 devices are useful for on–card regulation or any
other application where a regulated negative voltage at a modest
current level is needed. These regulators offer substantial advantage
over the common resistor/zener diode approach.

*SOP–8 is an internally modified SO–8 package.
Pins 2, 3, 6, and 7 are electrically common to the
die attach flag. This internal lead frame modifica-
tion decreases package thermal resistance and
increases power dissipation capability when
appropriatelymounted on a printed circuit board.
SOP–8 conforms to all external dimensions of the
standard SO–8 package.

APPLICATIONS INFORMATION
Design Considerations
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 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.
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
