Packages

Applications

The APL1117D/R is a low dropout three-terminal fixed

3.3V and 5.0V regulators with 1A output current

capability. In order to obtain lower dropout voltage

and faster transient response, which is critical for

low voltage applications , the APL1117D/R has been

optimized. The dropout voltage is guaranteed at a

maximum of 1.3V at 0.8A. Current limit is trimmed to

ensure specified output current and controlled short-

circuit current. On-chip thermal limiting provides pro-

tection against any combination of overload that would

create excessive junction temperatures. The

APL1117D/R is available in the industry standard 3-

pin SOT-223 and TO-252 the low profile surface mount

packages which can be used in applications where

space is limited.
