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.
