| TECHNICAL DATA KKA8137 DUAL 5.1V REGULATOR WITH DISABLE AND RESET The KKA8137 is a monolithic dual positive voltage regulator designed to provide fixed precision output voltages of 5.1 V at currents up to 1 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. Short circuit and thermal protections are included. * * * * * * * Output currents up to 1 A Fixed precision OUTPUT voltages 5.1 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 KKA8137A KK8137A Plastic Package chip TJ = -0 to 130C PIN ASSIGNMENT 7 6 5 4 3 2 1 OUTPUT 1 OUTPUT 2 RESET GROUND DISABLE DELAY CAP INPUT Tab connected to Pin 4 BLOCK DIAGRAM INPUT 1 PREFERENCE OUT 1 7 OUT 1 PROTECTION RESET 5 RESET CR 2 DELAY CAP 6 OUT 2 DISABLE 3 DISABLE OUT 2 4 1 KKA8137 MAXIMUM RATINGS* Symbol VIN VDIS VRST IO1,2 SC Tstg TJ * Parameter DC Input Voltage Pin 1 Disable Input Voltage Pin 3 Voltage at Pin 5 Short Circuit Output Current Storage Temperature Junction Temperature VIN = 7 V VIN = 16 V Min Max 20 20 20 1.6 1.0 Unit V V V A C C -65 0 150 150 Maximum Ratings are those values beyond which damage to the device may occur.
