| K78XX-500 Series WIDE INPUT NON-ISOLATED & REGULATED SINGLE POSITIVE/NEGATIVE OUTPUT multi-country patent protection RoHS FEATURES Efficiency Up To 96% Temperature Range: -40C to +85C No heat sink Required Pin-out compatible with LM78XX Linears Short circuit protection, Thermal Shutdown Low ripple and noise SIP Package Industry Standard Pinout MTBF>2,000,000 hours The K78xx-500 Series converters can also be used to convert a positive voltage into a negative voltage. Only two extra capacitors are required. Input voltage range can be lower than the output voltage for higher output voltages PRODUCT PROGRAM Part Number K7803-500 Input Voltage Range (VDC) 4.75-28 4.75-25 K7805-500 6.5-32 6.0-27 K78X6-500 8-32 6.0-25 K7809-500 11-32 7.0-23 K7812-500 15-32 7.0-20 K7815-500 18-32 7.0-17 Output Voltage (VDC) 3.3 -3.3 5.0 -5.0 6.5 -6.5 9.0 -9.0 12 -12 15 -15 Current (mA) 500 -400 500 -400 500 -300 500 -200 500 -200 500 -200 Efficiency(%) Vin (Min) 90 73 93 78 94 83 95 87 95 85 96 84 Vin (Max) 80 78 84 83 87 85 91 86 92 87 93 89 OUTPUT SPECIFICATIONS Item Test Conditions Vin= min. to max. at full load 10% to 100% load 20MHZ Bandwidth Min Typ 2 0.2 0.4 20 0.5 280 Positive Output Negative Output Internal IC junction -40 C to +85 C ambient 330 5 7 150 0.02 1000 Max 3 0.4 0.6 35 1.8 450 8 13 mVp-p W KHz mA C %/C F % Units APPLICATIONS The K78xx-500 Series high efficiency switching regulators are ideally suited to replace 78xx linear regulators and are pin compatible.
