800mA LOW DROPOUT POSITIVE

FIXED 3.3V REGULATOR

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.
