Description  
Features  
The GM78L00 series in positive voltage regulators are low-  
cost devices providing a simple solution for a wide variety  
of applications, which requires a regulated supply of up to  
100mA.  
Output Current up to 100mA  
Output Voltages 5V, 6V, 8V, 9V, 10V, 12V,  
15V, 18V and24V  
3- Terminal Regulators  
These virtually indestructible positive voltage regulators  
are protected by thermal shutdown and internal current-  
limiting. Most applications require no external components.  
No External Components Required  
Internal Thermal Overload Protection  
Internal Short Circuit Current-Limiting  
Available in TO-92, SOT-89 and SOP-8  
packages  
The GM78L00 is very versatile. To use them as fixed volt-  
age regulators in a wide range of applications, including  
both local and on-card regulation for elimination of noise  
and distribution problems associated with single-point regu-  
lation. They can also be used with power pass elements to  
make high current voltage regulators.  
The GM78L00 offers impressive performance advantages  
over old-fashioned zener diode-resistor combinations, pro-  
viding lower output impedance and reduced quiescent cur-

A common ground is required between the input and the output voltages. The  
input voltage must remain typically 2.0V above, the output voltage even during

APPLICATION INFORMATION  
Where:  
q = thermal resistance of the case between the reg-  
JC  
Design Considerations  
The GM78L00 series regulators have thermal overload  
protection from excessive power, internal short-circuit  
protection limits each circuit's maximum current, and  
output transistor safe-area protection for reducing the  
output current as the voltage across each pass transis-  
tor is increased.

q

JL  
the input lead to a point 1/16 inch below the regula-  
tor case.  
Although the internal power dissipation is limited, the  
junction temperature must be kept below the maximum  
specified temperature (125°C) in order to meet data  
sheet specifications.

Thermal Considerations  
The TO-92 molded package is capable of unusual high  
power dissipation due to the lead frame design.  
However, its thermal capabilities are generally over-  
looked because of a lack of understanding of the ther-  
mal paths from the semiconductor junction to ambient  
temperature.

While thermal resistance is normally specified for the  
device mounted 1cm above an infinite heat sink, very  
little has been mentioned of the options available to im-  
prove the conservatively rated thermal capability.An ex-  
planation of the thermal paths of the TO-92 will allow  
the designer to determine the thermal stress which is  
applying in any given application.

The TO-92 Package  
The TO-92 package thermal paths are complex. In addi-  
tion to the path through the molding compound to ambi-  
ent temperature, there is another path through the  
leads, in parallel with the case path, to ambient tem-  
perature, as shown in Figure 5.  
The total thermal resistance in this model is then:
