DESCRIPTION
The IRU1015 is a low dropout three-terminal adjustable
regulator with minimum of 1.5A output current capabil-
ity. This product is specifically designed to provide well
regulated supply for low voltage IC applications such as
486DX4 processor, P55C
speed bus termination and low current 3.3V logic sup-
ply. The IRU1015 is also well suited for other applica-
tions such as VGA and sound card. The IRU1015 is
guaranteed to have <1.3V dropout at full load current
making it ideal to provide well regulated outputs of 2.5V
to 3.3V with 4.75V to 7V input supply.
