APL1086
1.5A Low Dropout Fast Response Positive Adjustable Regulator and Fixed
1.8V, 2.5V, 2.85V and 3.3V
Features
General Description
The APL1086 is a low dropout three-terminal adjust-
able regulators with 1.5A output current capability.
In order to obtain lower dropout voltage and faster
transient response, which is critical for low voltage
applications , the APL1086 has been optimized.

Standard 3-pin SOT-223, TO-252 , TO-220 and
TO-263 Power Packages.
Current limit is trimmed to ensure specified output
current and controlled short-circuit current. On-chip
thermal limiting provides protection against any com-
bination of overload that would create excessive junc-
tion temperatures.
The APL1086 is available in the industry standard 3-
pin SOT-223, TO-252, TO-220 or TO-263 power
packages.
