„ GENERAL DESCRIPTION
The FSP1084 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 FSP1084 is available in 1.5V, 1.8V, 2.5V, 3.3V and
5.0V versions. The fixed versions integrate the adjust
resistors. It is also available in an adjustable version
which can set output voltage with two external
resistors.
The FSP1084 series is available in standard package
of TO263-2L, TO220-3L and TO252-2L.
