CM3131 Triple Linear
Voltage Regulator for DDR-I/-II Memory
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 applications • Lowest system cost and smallest footprint for DDR power solutions • VDDQ regulator/driver utilizes external N-FET to com 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 applicatio...
