IRU1015
1.5A LOW DROPOUT POSITIVE ADJUSTABLE REGULATOR DESCRIPTION
The IRU1015 is a low dropout three-terminal adjustable regulator with minimum of 1.5A output current capability. This product is specifically designed to provide well regulated supply for low
voltage IC applications such as 486DX4 processor, P55C I/O supply as well as high speed bus termination and low current 3.3V logic supply. The IRU1015 is also well suited for other applications 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.
