LM78XX/LM78XXA3-Terminal 1A Positive Voltage RegulatorFeaturesGeneral Description Output Current up to 1AThe LM78XX series of three terminal positive regulatorsare available in the TO-220 package and with severalfixed output voltages, making them useful in a widerange of applications. Each type employs internal currentlimiting, thermal shut down and safe operating area protection, making it essentially indestructible. If adequateheat sinking is provided, they can deliver over 1A outputcurrent. Although designed primarily as fixed voltageregulators, these devices can be used with external components to obtain adjustable voltages and currents. Output Voltages of 5, 6, 8, 9, 10, 12, 15, 18, 24 Thermal Overload Protection Short Circuit Protection Output Transistor Safe Operating Area ProtectionOrdering InformationProduct NumberOutput Voltage TolerancePackageOperating Temperature 4%TO-220-40 C to 125 M7815CTLM7818CTLM7824CTLM7805ACT 2%0 C to 125 15ACTLM7818ACTLM7824ACT 2006 Fairchild Semiconductor CorporationLM78XX/LM78XXA Rev. 1.01www.fairchildsemi.comLM78XX/LM78XXA 3-Terminal 1A Positive Voltage RegulatorMarch 2008
