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 pro-

vides protection against any combination of overload

and ambient temperatures that would create excessive

junction temperatures. It also includes a trimmed band-

gap 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.
