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.
