描述 Description

Key Features:Two Independent Regulated OutputsWide DC Supply Voltage of 3.0V to 10.0VAccurate Output VoltagesLow Tolerance Line (0.5%) and Load (0.5%) RegulationMax. Dropout of 0.6V at Rated CurrentIndependent Thermal and Current Limit ProtectionLoop Stability Independent of Output CapacitorType SMT Power PackageDescriptionThe LX8821 is a positive-voltage linear regulator with one fixed and one adjustable output featuring lowdropout and high accuracy.To maximize efficiency, the LX8821 accepts two supply voltage inputs for the VCONTROL and VPOWERsections. This configuration reduces power dissipation by operating the regulator near dropout (VPWR-VOUT = VDO = 0.4V @ 2A) while providing sufficient operating headroom for the control logic.
