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
dissipation by operating the regulator
near dropout (V

-V
OUT

DO
=
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.
Each channel can supply up to 2.5A
independently with a regulator design
optimized for system efficiency by
consuming minimal ground current
