PRELIMINARY GM78L00 100 mA POSITIVE VOLTAGE REGULATORS Wide range of Fixed Output Voltages Output Current up to 100 mA 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 series of positive voltage regulators are low-cost devices providing a simple solution for a wide variety of applications requiring a regulated supply of up to 100mA. These virtually indestructible positive voltage regulators are protected by thermal shutdown and internal current-limiting. Most applications require no external components. The GM78L00’s are very versatile. Use them as fixed voltage regulators in a wide range of applications, including local 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’s offer impressive performance advantages over oldfashioned zener diode-resistor combinations, providing lower output impedance and reduced quiescent current, along with lower noise.

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. The total thermal resistance in this model is then: ( θJA + θCA) ( θJL + θLA) θJA = θJA + θCA + θJL + θLA Thermal Considerations The TO-92 molded package is capable of unusually 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 1 cm above an infinite heat sink, very little has been mentioned of the options available to improve on the conservatively rated thermal capability. An explanation of the thermal paths of the TO-92 will allow the designer to determine the thermal stress he is applying in any given application. Where: θJC = thermal resistance of the case between the regulator die and a point on the case directly above the die location. θCA = thermal resistance between the case and air at ambient temperature. θJL = thermal resistance from regulator die through the input lead to a point 1/16 inch below the regulator case. θLA = total thermal resistance of the input/output ground leads to ambient temperature. θJA = junction to ambient thermal resistance. FIGURE 1. TO-92 Thermal Equivalent Circuit TJ 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 temperature, as shown in Figure 1. θJC θJL PE ( W) θCA θLA TA ORDERING INFORMATION OUTPUT VOLTAGE 5V 6V 8V PACKAGE TO-92 GM78L05-T92 GM78L06-T92 GM78L08-T92 GM78L09-T92 GM78L10-T92 GM78L12-T92 GM78L15-T92 GM78L18-T92 GM78L24-T92 SOT-89 GM78L05-ST89 GM78L06-ST89 GM78L08-ST89 GM78L09-ST89 GM78L10-ST89 GM78L12-ST89 GM78L15-ST89 GM78L18-ST89 GM78L24-ST89 SOP 8 GM78L05-S8 GM78L06-S8 GM78L08-S8 GM78L09-S8 GM78L10-S8 GM78L12-S8 GM78L15-S8 GM78L18-S8 GM78L24-S8 GM78L00 9V 10V 12V 15V 18V 24V Revision 1, May 2002 6 www.gammamicro.com
