DESCRIPTION
The IRU1010-33 is a low dropout three-terminal fixed out-
put regulator with minimum of 1A output current capabil-
ity. This product is specifically designed to provide well
regulated supply for low voltage IC applications such as
VGA, sound & DVD cards. The IRU1010-33 is guaran-
teed to have <1.3V dropout at full load current making it
ideal to provide well regulated with 4.75V to 7V input
supply. The IRU1010-33 is specifically designed to be
stable with low cost aluminum capacitors while main-
taining stability with low ESR tantalum caps.
