APL1084 m o c Load Regulation :0.05% Typ. Line Regulation : 0.03% Typ. Low Dropout Voltage: 1.3V Typ. at IOUT =5A Trimmed Current Limit : 5A Typ. at TJ=125 °C On-Chip Thermal Limiting : 150 °C Typ. Standard 3-pin TO-220, TO-252 and TO-263 Power Packages ! Lead Free Available (RoHS Compliant) voltageapplications, the APL1084 has been optimized. The output available voltage range of adjustable version is from 1.25~5.75V with an input supply below 7V, and the fixed 3.3V output voltage device is also available. Current limit is trimmed to ensure specified output current and controlled short-circuit current. Onchip thermal limiting provides protection against any combination of overload that would create excessive junction temperatures. The APL1084 is available in both the through-hole and surface mount versions of the industry standard 3-pin TO-220,TO-252 and TO263 power packages. Applications ! ! ! ! !
