The MC78L00, A Series of positive voltage regulators are inexpensive,  
easy–to–use devices suitable for a multitude of applications that require a  
regulated supply of up to 100 mA. Like their higher powered MC7800 and  
MC78M00 Series cousins, these regulators feature internal current limiting  
and thermal shutdown making them remarkably rugged. No external  
components are required with the MC78L00 devices in many applications.  
These devices offer a substantial performance advantage over the  
traditional zener diode–resistor combination, as output impedance and  
quiescent current are substantially reduced.

* SOP–8 is an internally modified SO–8 package.  
Pins2,3,6,and7areelectricallycommontothedie  
attach flag. This internal lead frame modification  
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.
