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