KA78XXE/KA78XXAE 3-Terminal 1A Positive Voltage RegulatorMay 2006KA78XXE/KA78XXAE3-Terminal 1A Positive Voltage RegulatorFeatures■Output Current up to 1A ■Output Voltages of 5, 6, 8, 9, 10, 12, 15, 18, 24V ■Thermal Overload Protection ■Short Circuit Protection■Output Transistor Safe Operating Area Protection DescriptionThe KA78XXE/KA78XXAE series of three-terminal posi-tive regulator are available in the TO-220/D-PAK packageand with several fixed output voltages, making them use-ful in a wide range of applications. Each type employsinternal current limiting, thermal shut down and safeoperating area protection, making it essentially inde-structible. If adequate heat sinking is provided, they candeliver over 1A output current. Although designed pri-marily as fixed voltage regulators, these devices can beused with external components to obtain adjustable volt-ages and currents.Ordering InformationPart NumberKA7805E / KA7806E KA7808E / KA7809EKA7810EKA7812E / KA7815EKA7818E / KA7824EKA7805AE / KA7806AEKA7808AE / KA7809AEKA7810AE KA7812AE/KA7815AE KA7818AE/KA7824AEKA7805ER / KA7806ERKA7808ER / KA7809ERKA7812ER±4%D-PAK±2%Output Voltage Tolerance±4%PackageTO-220Operating Temperature0 to +125°C©2006 Fairchild Semiconductor Corporation1www.fairchildsemi.com
