CP10843.3VA

CP1084 5A Dropout Linear Regulator General Description The CP1084 is a series of low dropout positive voltage regulators with a maximum dropout of 1.5V at 5A of load current. The series features on-chip thermal limiting which provides protection against any combination of overload and ambient temperatures that would create excessive junction temperatures. It also includes a trimmed bandgap reference and a current limiting circuit. The CP1084 is available in 1.5V, 1.8V, 2.5V, 3.3V, and 5.0Vversions. The fixed versions integrate the adjust resistors. It is also available in an adjustable version which can set the output voltage with two external resistors. The CP1084 series is available in standard packages of TO-263-2L, TO-252.
