General Description
The APL1085 is a low dropout three-terminal adjustable
regulator with 3A output current capability. In order to ob-
tain lower dropout voltage and faster transient response
which is critical for low voltage applications, the APL1085
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 cur-
rent and controlled short-circuit current. On-chip thermal
limiting provides protection against any combination of
overload that would create excessive junction
temperatures.
The APL1085 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.
