100 mA Negative 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.
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.
No External Components Required
Internal Short Circuit Current Limiting
Internal Thermal Overload Protection
Low Cost
Complementary Positive Regulators Offered (MC78L00 Series)
Available in Either ±5% (AC) or ±10% (C) Selections
Representative Schematic Diagram
*Automotive temperature range selections are available with special test conditions
and additional tests in 5, 12 and 15 V devices. Contact your local ON Semiconductor
sales office for information.

*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
appropriately mounted on a printed circuit board.
SOP–8 conforms to all external dimensions of the
standard SO–8 package.
