General Description

Applications

The APL1085 is a low dropout three-terminal adjust-

able regulator with 3A output current capability. In

order to obtain lower dropout voltage and faster tran-

sient response, which is critical for low voltage

applications, the APL1085 has been optimized. The

output available voltage range of adjustable version

is from 1.25~5.75V with an input supply below 7V ,

and the fixed 3.3V output voltage device is also

available.

Current limit is trimmed to ensure specified output

current and controlled short-circuit current. On-chip

thermal limiting provides protection against any com-

bination of overload that would create excessive junc-

tion temperatures.

The APL1085 is available in both the through-hole

and surface mount versions of the industry standard
