| TECHNICAL DATA KKA8138A 5.1V +12V REGULATOR WITH DISABLE AND RESET The KKA8138A is a monolithic dual positive voltage regulator designed to provide fixed precision output voltages of 5.1V and 12V at currents up to 1A. Output 2 can be disabled by TTL input. Short circuit and thermal protections are included in all the versions. * * * * * * * * Output currents up to 1 A Fixed precision OUTPUT 1 voltages 5.1 V 2% Fixed precision OUTPUT 2 voltages 12 V 2% OUTPUT 1 with RESET facility OUTPUT 2 with DISABLE by TTL input Short circuit protection at both outputs Thermal protection Low drop output voltage TO-220AB/7 HEPTAWAT (Plastic Package) ORDERING INFORMATION KKA8138A Plastic Package TJ = -0 to 130C PIN ASSIGNMENT 7 6 5 4 3 2 1 OUTPUT 1 OUTPUT 2 N.C.
