Applications
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.
The device is available in an adjustable version and
fixed output voltages of 1.8V, 2.5V,2.85V and 3.3V,
the output available voltage range is from 1.25~10.
7V with an input supply below 12V. Dropout voltage
is guaranteed at a maximum of 1.45V at 1.5A.
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.
• Active SCSI Terminators
• Low Voltage Logic Supplies
• Battery-Powered Circuitry
• Post Regulator for Switching Power Supply
