CS5233-3 - Dual Input Linear Regulator
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.
The CS5233 3 is intended to provide power to an ASIC on a PCI Network Interface Card (N
