The SP1085 is a 3A low dropout linear regulator with a maximum dropout of 1.5V. It 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.
The SP1085 is a series of low dropout positive voltage regulators featuring on-chip thermal shutdown, current limiting, and a bandgap reference. It supports output currents up to 3A with a typical dropout voltage of 1.3V at that load.
The device is available in fixed output voltages (1.5V, 1.8V, 2.5V, 2.85V, 3.3V, 5.0V) and an adjustable version. It comes in three standard packages: TO-263-3L, TO-220, and TO-252.
