LX8817

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.Each channel can supply up to 2.5A independently with a regulator design optimized for system efficiency by consuming minimal ground current and directing quiescent current to the load.

The LX8817 features on-chip trimming of the internal voltage reference, enabling precise output voltages, typically ±1% of it's specified value.

Power sequencing logic ensures proper startup regardless of the level of VCTRL or VPWR. The LX8817 outputs remain off while VPWR < 2.7V. Thermal and Short Circuit Current Protection are integrated on-chip and operate independently for each regulator output.

The LX8817 regulator is stable with a low-value output capacitor, typically 10mF tantalum or ceramic on the outputs, allowing designers flexibility in external component selection.Linfinity's S-PAK power package offers maximum power dissipation and ease of assembly using surface mount technology.
