General Description
The APL1117 is a low dropout three-terminal adjust-
able regulators with 1A output current capability. In
order to obtain lower dropout voltage and faster tran-
sient response, which is critical for low voltage ap-
plications , the APL1117 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 of an adjustable ver-
sion is from 1.25~10.7V with an input supply below
12V. Dropout voltage is guaranteed at a maximum of
1.3V at 1A. Current limit is trimmed to ensure speci-
fied output current and controlled short-circuit current.
On-chip thermal limiting provides protection against
any combination of overload that would create exces-
sive junction temperatures. The APL1117 is available
in the industry standard 3-pin TO-220, TO-252, TO-
263, and the low profile surface mount SOT-223
power packages which can be used in applications
where space is limited.

Note 1 : See thermal regulation specifications for changes in output voltage due to heating effects. Load line regulations are mea-
sured 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.
