TYPICAL APPLICATION

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.
