Product 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. 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.
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 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 applications
• Over temperature and reverse current protection
• Over current protection for VSTBY and VTT regulator
• Available in 8 lead and 14 lead PSOP packages
• Lead-free versions available
Applications
• Desktop PCs, notebooks, and workstations
• Set top boxes, digital TVs, printers
• Embedded systems
