DESCRIPTION
The IRU1117-33 is a low dropout three-terminal fixed out-
put regulator with minimum of 800mA output current ca-
pability. This product is specifically designed to provide
well regulated supply for low voltage IC applications such
as VGA, sound & DVD cards. The IRU1117-33 is guar-
anteed to have <1.2V dropout at full load current making
it ideal to provide well regulated with 4.75V to 7V input
supply. The IRU1117-33 is specifically designed to be
stable with low cost aluminum capacitors while main-
taining stability with low ESR tantalum caps.
