DESCRIPTION
The IRU1117 is a low dropout, three-terminal adjustable
regulator with minimum of 800mA output current capa-
bility. This product is specifically designed to provide
well regulated supply for low voltage IC applications such
as high speed bus termination and low current 3.3V logic
supply. The IRU1117 is also well suited for other applica-
tions such as VGA and sound cards. The IRU1117 is
guaranteed to have <1.2V dropout at full load current
making it ideal to provide well regulated outputs of 2.5V
to 3.6V with 4.75V to 7V input supply.
