General Description
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.
