The APL1084 is a low dropout three-terminal adjustable

regulator with 5A output current capability. In order to ob-

tain lower dropout voltage and speed up transient

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 to 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 protec-

tion against any combination of overload that would cre-

ate excessive junction temperatures. The APL1084 is

available 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.
