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.
