General Description
The APL1086 is a low dropout three-terminal adjustable 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 combination of overload that would create excessive junction temperatures.
The APL1086 is available in the industry standard 3pin SOT-223, TO-252, TO-220 or TO-263 power
packages.

Note 1: See thermal regulation specifications for changes in output voltage due to heating effects. Load line regulations are measured at a constant junction temperature by low duty cycle pulse testing.
Note 2: Dropout voltage is specified over the full output current range of the device. Dropout voltage is defined as the minimum input/
output differential measured at the specified output current. Test points and limits are also shown on the Dropout Voltage curve.
Note 3: Minimum load current is defined as the minimum output current required to maintain regulation.
