DESCRIPTION
The IRU1010 is a low dropout, three-terminal adjustable
regulator with minimum of 1A output current capability.
This product is specifically designed to provide well regu-
lated supply for low voltage IC applications such as high
speed bus termination and low current 3.3V logic sup-
ply. The IRU1010 is also well suited for other applica-
tions such as VGA and sound cards. The IRU1010 is
guaranteed to have <1.3V 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.
