Typically at 5A Current Limiting and Thermal Protection Output Current: 5A Current Limit:.5A Operating Junction Temperature Range:0 to 5 o C Line Regulation: 0.05% (Typical) Load Regulation: 0.% (Typical) Available in RoHS Compliant, Lead Free Packaging Applications OUTPUT ADJ/GND High Efficiency Linear Regulators Battery Chargers Post Regulation for Switching Supply Microprocessor Supply Desktop PCs, RISC and Embedded Processors Supply general Description The SP084 is a series of low dropout positive voltage regulators with a maximum dropout of.5 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 SP084 is available in.5,.8,.5,.85,. and 5.0 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 SP084 series is available in standard packages of TO--, TO-0 and TO-5.
