DESCRIPTION |
| |
The TJ3212 is a dual-output low noise linear regulator designed to meet SSTL-2 and SSTL-3 specifications for DDR-SDRAM VDDQ supply and termination voltage VTT supply. With integrated power MOSFETs the TJ3212 can source up to 2A of VDDQ continuous current, and source or sink up to 2A VTT continuous current. The typical dropout voltage for VDDQ is 500mV at 2A load current.
The TJ3212 provides excellent full load regulation and fast response to transient load changes. It also has built-in over-current limits and thermal shutdown at 170”ĘC.
The TJ3212 supports Suspend-To-RAM (STR) and ACPI compliance with Shutdown Mode which tri-states VTT to minimize quiescent system current.
The TJ3212 is available in a space saving TDFN-8 and SOIC-8 surface mount packages. Low thermal resistance allows them to withstand high power dissipation at 85”ĘC ambient. The TJ3212 can operate over the industrial ambient temperature range of -40”ĘC to 85”ĘC.
