Gamma GM78L05S8B Positive voltage regulator Datasheet

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

CO**
0.33µF
GND
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
the low point on the input ripple voltage.
* CIN is required if regulator is located an appreciable distance from power supply
filter.
** CO is not needed for stability; however, it does improve transient response.

APPLICATION INFORMATION
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
Where:
qJC = thermal resistance of the case between the regulator die and a point on the case directly above the
die location.
qCA = thermal resistance between the case and air at
ambient temperature.
output current as the voltage across each pass transistor is increased.
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.
qJL = thermal resistance from regulator die through
the input lead to a point 1/16 inch below the regulator case.
qLA = total thermal resistance of the input/output
ground leads to ambient temperature.
qJA = junction to ambient thermal resistance.
Thermal Considerations
The TO-92 molded package is capable of unusual high
power dissipation due to the lead frame design.
TJ
However, its thermal capabilities are generally overlooked because of a lack of understanding of the thermal paths from the semiconductor junction to ambient
temperature.
JC
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 explanation 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 addition to the path through the molding compound to ambient temperature, there is another path through the
GM78L00 SERIES
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:
