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 to 10.7V with an input
supply below 12V. Dropout voltage is guaranteed at a

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 tha t would create excessi ve junc tion
temperatures.

Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020C for
MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and halogen
free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).

Note 3: 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 4: 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 5: Minimum load current is defined as the minimum output current required to maintain regulation.
