General Description
The HPL1117 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 HPL1117 has been optimized. The
device is available in an adjustable version and fixed
output voltages of 1.8V, 2.5V, 2.85V, 3.3V and 5V.
The output available voltage range of an adjustable
version is from 1.25~10.7V with an input supply be-
low 12V. Dropout voltage is guaranteed at a maxi-
mum 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 cre-
ate excessive junction temperatures. The HPL1117
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 applica-
tions 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.
