Product Description
The CM3202−00 is a dual−output low noise linear regulator designed to meet SSTL−2 and SSTL−3 specifications for DDR−SDRAM VDDQ supply and termination voltage VTT supply. With integrated power MOSFET’s, the CM3202−00 can source up to 2 A of VDDQ continuous current, and source or sink up to 2 A VTT continuous current. The typical dropout voltage for VDDQ is 500 mV at 2 A load current.
