The RT9185 series are efficient, precise triple-channel CMOS LDO regulators specifically designed for motherboard application. The device is intended to powering the standby voltage in which 3.3V_PCI, 2.5V_Clock and 1.8V_ICH2 or 1.5V_ICH4 core voltage of the PC based computer system. Moreover, it is also optimized for CD/ DVD-ROM, CD/RW, XDSL Router or IA equipments applications. The regulator outputs are capable of sourcing 1.5A, 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 power applications. The other features include faster transient response, 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. |
