CM3121 - Dual Linear Voltage Regulator

Datasheet Summary

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 2.8V to 3.6V supply for DDR-I memory and 2.2V to 2.8V for 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 regu.
