HPL1117
1A Low Dropout Fast Response Positive Adjustable Regulator and Fixed
1.8V, 2.5V, 2.85V, 3.3V and 5V
Features
General Description
• Guaranteed Output Voltage Accuracy within 2% The HPL1117 is a low dropout three-terminal adjust-
able regulators with 1A output current capability. In
• Fast Transient Response
order to obtain lower dropout voltage and faster tran-
• Guaranteed Dropout Voltage at Multiple
Currents
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
• Load Regulation : 0.1% Typ.
• Line Regulation : 0.03% Typ.
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 Dropout Voltage : 1.1V Typ. at IOUT =1A
• Current Limit : 1A Typ. at TJ=25°C
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
• On-Chip Thermal Limiting : 150°C Typ.
• Adjustable Output : 1.25~10.7V
current. On-chip thermal limiting provides protection
against any combination of overload that would cre-
ate excessive junction temperatures. The HPL1117
• Standard 3-pin TO-220, TO-252, TO-263 and
SOT-223 Power Packages
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.
