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.
