Internal Short Circuit Protection that limits the maximum current the circuit will pass. In many low current applications, compensation capacitors are not required. However,it is recommended that the regulator input be bypassed with a capacitor if the regulator is connected to the power supply filter with long wire lengths, or if the output load capacitance is large. An input bypass capacitor should be selected to provide good high frequency characteristics to insure stable operation under all load conditions. A 0.33µF or larger tantalum, mylar, or other capacitor having low internal impedance at high frequencies should be chosen. The bypass capacitor should be mounted with the shortest possible leads directly across the regulator's input terminals. Normally good construction techniques should be used to minimize ground loops and lead resistance drops since the regulator has no external sense lead. Bypassing the output is also recommended.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. * C 1 is required if regulator is located an appreciable distance from power supply filter.* C O improves stability and transient response.Figure 1.Positive And Negative RegulatorFigure 2.Typical ApplicationLM78LXXA MC78LXXALM79LXXA MC79LXXAIMC79LXXA LM79LXXAMC79LXXA/LM79LXXA Mechanical DimensionsPackageDimensions in millimetersTO-929MC79LXXA/LM79LXXAMechanical Dimensions (Continued)PackageDimensions in millimeters8-SOP10MC79LXXA/LM79LXXA Mechanical Dimensions (Continued)PackageDimensions in millimetersSOT-8911MC79LXXA/LM79LXXA12/11/02 0.0m 001Stock#DSxxxxxxxx2002 Fairchild Semiconductor CorporationLIFE SUPPORT POLICYFAIRCHILD’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS WITHOUT THE EXPRESS WRITTEN APPROVAL OF THE PRESIDENT OF FAIRCHILD SEMICONDUCTOR CORPORATION.

These regulators can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each type employs internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltage and currents.L7800SERIESPOSITIVE VOLTAGE REGULATORSL7800 SERIESTable 1: Absolute Maximum RatingsAbsolute Maximum Ratings are those values beyond which damage to the device may occur.
