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-

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.

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.

Figure 5. TO-92 Thermal Equivalent Circuit
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:
