CM3202-02
DDR VDDQ and VTT
Termination Voltage
Regulator
Product Description
The CM3202â02 is a dualâoutput low noise linear regulator
designed to meet SSTLâ2 and SSTLâ3 specifications for
DDRâSDRAM VDDQ supply and termination voltage VTT supply.
With integrated power MOSFETs the CM3202â02 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.
The CM3202â02 provides excellent full load regulation and fast
response to transient load changes. It also has builtâin overâcurrent
limits and thermal shutdown at 170°C.
The CM3202â02 supports SuspendâToâRAM (STR) and ACPI
compliance with Shutdown Mode which triâstates VTT to minimize
quiescent system current.
The CM3202â02 is available in a space saving WDFN8 surface
mount packages. Low thermal resistance allows them to withstand
high power dissipation at 85°C ambient. The CM3202â02 can operate
over the industrial ambient temperature range of â40°C to 85°C.
