general Description
The SP1086 is a series of low dropout positive voltage regulators with a maximum dropout of 1.5V at 1.5A of load
current. The series features on-chip thermal shutdown. It also includes a bandgap reference and a current limiting
circuit. The SP1086 is available in 1.5V, 1.8V, 2.5V, 3V, 3.3V, and 5.0V versions. The fixed versions integrate the
adjust resistors. It is also available in an adjustable version, which can set the output voltage with only two external
resistors. The SP1086 series is available in standard packages of TO-263-3, TO-220 , and TO-252.
