General Description
The S
P1085
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 S
P1085
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 S
P1085
series is
available in standard packages of TO-263-3L, TO-220 and TO-252.
