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-
s i e n t r e s p o n s e , w h i c h i s c r i t i c a l f o r l o w
voltageapplications, the APL1084 has been optimized.
The output available voltage range of adjustable ver-
sion 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 specified
output current and controlled short-circuit current. On-
chip thermal limiting provides protection against any
combination of overload that would create excessive
junction temperatures. The APL1084 is available in
both the through-hole and surface mount versions of
the industry standard 3-pin TO-220,TO-252 and TO-
263 power packages.
