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.
