DESCRIPTION

The LX8817 is a dual channel positive-voltage linear regulator. This dual regulator has one fixed output coupled with an adjustable output. Each channel features low-dropout and high accuracy.

The LX8817 utilizes dual inputs that

can be used as separate sources for the control and power sections. This configuration reduces power dissipation by operating the regulator near dropout (VPWR-VOUT = VDO = 0.6V @ 2.5A) while providing sufficient operating headroom for the control logic.

The LX8817 provides designers with an efficient flexible power management solution, minimal printed circuit board area, and shorter design cycles.
