Description
The GM78L00 series in positive voltage regulators are lowcost devices providing a simple solution for a wide variety of applications, which requires a regulated supply of up to 100mA. These virtually indestructible positive voltage regulators are protected by thermal shutdown and internal currentlimiting. Most applications require no external components. The GM78L00 is very versatile. To use them as fixed voltage 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 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-
Features
Output Current up to 100mA Output Voltages 5V, 6V, 8V, 9V, 10V, 12V, 15V, 18V and24V 3- Terminal Regulators No External Components Required Internal Thermal Overload Protection Internal Short Circuit Current-Limiting Available in TO-92, SOT-89 and SOP-8 packages
TYPIC APPLICATION CIRCUITS
CIN* 0.33µF
CO**
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 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. 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 overlooked because of a lack of understanding of the thermal 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 improve 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 leads, in parallel with the case path, to ambient temFigure 5.

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. 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.
