TECHNICAL DATA KKA8133A DUAL +5.1V +8V REGULATOR WITH DISABLE AND RESET The KKA8133A is a monolithic dual positive voltage regulator designed to provide fixed precision output voltages of 5.1 V and 8 V at currents up to 0.75 A. An internal reset circuit generates a reset pulse when the output 1 decreases below the regulated voltage value. Output 2 can be disabled by TTL input. • • • • • • • • Output currents up to 0.75 A Fixed precision OUTPUT 1 voltage 5.1 V ± 2% Fixed precision OUTPUT 2 voltage 8 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 ORDERING INFORMATION KKA8133A Plastic Package KK8133A chip TJ = -0° to 130°C PIN ASSIGNMENT 7 6 5 4 3 OUTPUT 1 2 INPUT 2 1 INPUT 1 OUTPUT 2 N.C.
