Overview
PRELIMINARY CM3121 Dual Linear Voltage Regulator for DDR-I and DDR-II Memory Features Fully integrated power solution for DDR memory ICs • Ideal for DDR-I (2.
5VDDQ) and DDR-II (1.
8VDDQ) • Lowest system cost and smallest footprint with just two external output capacitors • Two linear regulators: -V regulator with a maximum output current www.
DataSheet4U.
com DDQ of 1.
5A shared by DRAM and VTT regulator - source-sink VTT regulator with maximum output current of 0.
5A (DDR-I) or 0.
3A (DDR-II) • Fault output indicates overcurrent condition in either regulator, under voltage lock-out and overtemperature condition • Reverse current protection if host is powered off • PSOP-8 package with integrated heat spreader • Lead-free versions available • Product Description The CM3121 provides an integrated power solution for DDR-I and DDR-II memory systems in consumer electronics applications.
The CM3121 is ideal for a 2.
