general Description

The SP1085 is a series of low dropout positive voltage regulators with a maximum dropout of 1.5V at 3A of load current. The series features on-chip thermal shutdown. It also includes a bandgap reference and a current limiting circuit. The SP1085 is available in 1.5V, 1.8V, 2.5V, 2.85V, 3.3V, 5.0V and adjustable versions. The fixed versions integrate the adjust resistors. The adjustable version can set the output voltage with two external resistors. The SP1085 series is available in standard packages of TO-263-3L, TO-220 and TO-252.
