Triple Linear Voltage Regulator for DDR-I/-II Memory
Product Description
Features
The CM3131 family of all-linear regulators provides
an integrated power solution for DDR-I/-II memory
systems in both run-time and standby modes of
operation. The CM3131 is ideal for designs
incorporating both a main 3.3V and a standby (3.3V
or 5V) supply. The CM3131 features three
independent linear regulators for VDDQ, VTT and VSTBY
supply regulation and will maintain an accuracy of
1% across the operating temperature range.

•
•
•
Integrated power solution for DDR-I and DDR-II
memory systems with few external components
Three all-linear regulators for VDDQ, VTT and
VSTBY power supply applications
Lowest system cost and smallest footprint for
DDR power solutions
VDDQ regulator/driver utilizes external N-FET to
provide up to 15A current at 2.5V/1.8V
VTT source/sink regulator provides up to 2A at
1.25V for DDR-I systems or 0.65A at 0.9V for
the DDR-II memory controller (not DDR-II
memory)
LDO standby regulator provides up to 500mA at
2.5V for DDR-I and at 1.8V for DDR-II systems
Can be ganged for higher current applications
Over temperature and reverse current protection
Over current protection for VSTBY and VTT
regulator
The CM3131 is offered in two configurations. The
CM3131-01/11 drives a single external N-FET on a
single VDDQ rail. The CM3131-02 drives two external
unmatched N-FETs on two VDDQ rails. Each VDDQ rail
incorporates an adjustment pin (SENSE) to enable
setting VDDQ in the 2.2V to 2.8V range, supporting
DIMMs with different supply requirements or DDR-II
type devices.

The CM3131-01/11 is available in 8-lead PSOP
package and the CM3131-02 is available in 14-lead
PSOP package.

CM3131
Functional Description
1.25V to or from the DDR-I bus termination resistors.
For DDR-II applications, the regulator sinks or
sources 0.65A at 0.9V. The VTT output voltage
accurately tracks VDDQ/2 to 1%. When there is no
VCC provided, VTT is powered down and its output is
0V. This regulator has overload current limiting of
2.5A.
The CM3131-01 / -11 and CM3131-02 provide
power for DDR-I/DDR-II memories from three
voltage regulators on-chip with either one or two
external N-FETs respectively. There is an over-
temperature thermal shutdown if any of the
regulators overheat. Each regulator has reverse
current protection in the event of any being shut
down.
The standby regulator is a LDO regulator that is
powered from a standby voltage, VSTBY, of 3.3V or
5V, and supplies a regulated output of up to 500mA
to the VDDQ of the DDR memory to enable it to retain
its contents during the standby mode. It provides
2.5V for DDR-I and 1.8V for DDR-II.
The linear regulator-driver/s with external N-FET/s
can provide up to 15A at 2.5V/1.8V for the VDDQ of
DDR-I/-II memory, from an input supply voltage of
2.8V-3.6V. An external feedback resistor divider,
connected to the SENSE1 pin, enables selection of
VDDQ output voltages from 2.2V to 2.8V for use with
DDR-I memories requiring other than 2.5V for VDDQ
VDDQ = 1.25V x (R1+R2)/R2. When SENSE1 is
connected to GND or left open, VDDQ is fixed at
2.50V (and VTT at 1.25V). For DDR-II operation,
VDDQ can be set from 1.7V to 1.9V.
The CM3131-01 and CM3131-11 differ with regards
the selection of truth table for determining which S0-
S5 sequencing matrix the chip is set for. The
CM3131-02 has both EN and SEL pins to more
accurately define each Sx stage without monitoring
the VCC or VSTBY voltages.
.
The VTT regulator is a linear source-sink regulator
powered from the VDDQ output that supplies the VTT
supply required by DDR-I memory termination
resistors. This regulator sinks or sources up to 2A at
Two CM3131s can be ganged together to provide
V
DDQ power to dual channels of DDR memory, and
the memory controller chip of any chip set.
