CM3131 - Triple Linear Voltage Regulator

Datasheet Summary

Description

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.

Features

  • 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.
