RT9185应用电路

The RT9185 series are  efficient, precise triple-channelCMOS LDO regulators specifically designed for mother-board applicaTIon. The device is intended to powering thestandby voltage in which 3.3V_PCI,  2.5V_Clock and1.8V_ICH2 or 1.5V_ICH4 core voltage of the PC basedcomputer system. Moreover, it is also opTImized for CD/DVD-ROM, CD/RW, XDSL Router or IA equipmentsapplicaTIons. The regulator outputs are capable of sourcing1.5A, 0.8A and 0.3A of output current respecTIvely.

The RT9185 also works with low-ESR ceramic capacitors,reducing the amount of board space necessary for powerapplications. The other features include faster transientresponse, low dropout voltage, high output accuracy,current limiting and thermal shutdown protections.The RT9185 regulators are available in fused SOP-8,5-lead TO-252 and 5-lead TO-263 packages.
