APL1117

1A Low Dropout Fast Response Positive Adjustable Regulator and Fixed

1.8V, 2.5V, 2.85V and 3.3V

Features

General Description

• Guaranteed Output Voltage Accuracy within 2% The APL1117 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 APL1117 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 and 3.3V. The

output available voltage range of an adjustable ver-

sion is from 1.25~10.7V with an input supply below

• Low Dropout Voltage : 1.1V Typ. at IOUT =1A

• Current Limit : 1A Typ. at TJ=25°C

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 : 150°C Typ.

• Adjustable Output : 1.25~10.7V

On-chip thermal limiting provides protection against

any combination of overload that would create exces-

sive junction temperatures. The APL1117 is available

• Standard 3-pin TO-220, TO-252, TO-263 and

SOT-223 Power Packages

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.
