CS5233-3 Description
CS5233−3 500 mA and 1.5 A, 3.3 V Dual Input Linear Regulator with Auxiliary Control The CS5233−3 provides a glitch−free 3.3 V output from one of three possible supplies, (VIN, VSB and 3.3 VAUX). An on−chip linear regulator powers the output when either VIN or VSB is available. Otherwise AuxDrv turns on an external PFET, which connects the 3.3 VAUX supply to the output.
