General Description
The APL1084 is a low dropout three-terminal adjust-
able regulator with 5A output current capability. In
order to obtain lower dropout voltage and faster tran-
sient response, which is critical for low voltage

applications, the APL1084 has been optimized. The
output available voltage range of adjustable version
is from 1.25~5.75V with an input supply below 7V,
and the fixed 3.3V output voltage device is also
available. Current limit is trimmed to ensure speci-
fied output current and controlled short-circuit current.
On-chip thermal limiting provides protection against
any combination of overload that would create ex-
cessive junction temperatures. The APL1084 is avail-
able in both the through-hole and surface mount ver-
sions of the industry standard 3-pin TO-220,TO-252
and TO-263 power packages.
