The APL1084 is a low dropout three-terminal adjustable
regulator with 5A output current capability. In order to
obtain 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
versions of the industry standard 3-pin TO-220,TO-252,
and TO-263 power packages.
