Ceramate CP10841.8VA 5a dropout linear regulator Datasheet

CP1084
5A Dropout Linear Regulator
General Description
Features
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.
