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 shortcircuit current. On-chip thermal limiting provides protection against any combination of overload that would
create excessive junction temperatures. The
APL1117D/R is available in the industry standard 3pin SOT-223 and TO-252 the low profile surface mount
packages which can be used in applications where
space is limited.

Note 1: See thermal regulation specifications for changes in output voltage due to heating effects. Load line regulations are mea-
sured at a constant junction temperature by low duty cycle pulse testing.
Note 2: Dropout voltage is specified over the full output current range of the device. Dropout voltage is defined as the minimum input/
output differential measured at the specified output current. Test points and limits are also shown on the Dropout Voltage curve.
Note 3: Minimum load current is defined as the minimum output current required to maintain regulation.
