General Description
The APL1117 is a low dropout three-terminal adjustable
regulators with 1A output current capability. In order to
obtain lower dropout voltage and faster transient
response, which is critical for low voltage applications,
the APL1117 has been optimized. The device is available
in an adjustable version and fixed output voltages of 1.2V,
1.8V, 2.5V, 2.85V, 3.3V, and 5V. The output available volt-
age range of an adjustable version is from 1.25 to 10.7V
with an input supply below 12V. Dropout voltage is guar-
anteed at a maximum of 1.3V at 1A. 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 APL1117 is
available in the industry standard 3-pin TO-220, TO-252-
3, TO-263-3, and the low profile surface mount SOT-223
power packages which can be used in applications where
space is limited.

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-020D 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 2: 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 3: 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 4: Minimum load current is defined as the minimum output current required to maintain regulation.
