| Solved by SP1084 TM 5A Low Dropout Linear Regulator TO-263-3 features Low Dropout Voltage: 1.3V Typically at 5A Current Limiting and Thermal Protection Output Current: 5A Current Limit: 6.5A Operating Junction Temperature Range:0 to 125oC Line Regulation: 0.015% (Typical) Load Regulation: 0.2% (Typical) Available in RoHS Compliant, Lead Free Packaging 3 2 1 INPUT OUTPUT ADJ/GND Applications High Efficiency Linear Regulators Battery Chargers Post Regulation for Switching Supply Microprocessor Supply Desktop PCs, RISC and Embedded Processors Supply general Description The SP1084 is a series of low dropout positive voltage regulators with a maximum dropout of 1.5V at 5A of load current. The series features on-chip thermal limiting which provides protection against any combination of overload and ambient temperatures that would create excessive junction temperatures. It also includes a trimmed band-gap reference and a current limiting circuit. The SP1084 is available in 1.5V, 1.8V, 2.5V, 2.85V, 3.3V and 5.0V versions. The fixed versions integrate the adjustment resistors. It is also available in an adjustable versio n which can set the output voltage with two external resis tors. The SP1084 series is available in standard packages of TO-263-3, TO-220 and TO-252. TO-263-3 TO-252 TO-220 Figure .
