The series features on-chip thermal limiting which provides protection against any bination 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 .
