FAN1655 3A DDR Bus Termination Regulator January 2006 FAN1655 3A DDR Bus Termination Regulator Description The FAN1655 is a low-cost bi-directional LDO specically designed for terminating DDR memory bus. It can both sink and source up to 2.1A continuous, 3A peak, providing enough current for most DDR applications. Load regulation meets the JEDEC spec, VTT = VREFOUT ± 40mV. The FAN1655 includes a buffered reference voltage capable of supplying up to 5mA current. On-chip thermal limiting provides protection against a combination of power overload and ambient temperature that would create an excessive junction temperature. A shutdown input puts the FAN1655 into a low power mode. The FAN1655 regulator is available in a power-enhanced eTSSOP-16, standard SOIC-14, and an 8-Lead MLP package. Features ■ Sinks and sources 2.1A continuous, 3A peak ■ 0 to +125°C operating temperature range ■ 5mA Buffered VREFOUT = VDDQ/2 ■ Load regulation: VTT = VREFOUT ± 40mV ■ On-chip thermal limiting ■ Low Cost SO-14, Power-Enhanced eTSSOP or 8-pin 5x6mm MLP packages ■ Low-Current Shutdown Mode ■ Output Short Circuit Protection Applications ■ DDR Terminator VTT supply Ordering Information Part Number FAN1655M FAN1655MX FAN1655MTF FAN1655MTFX FAN1655MPX Temperature Range 0°C to 125°C 0°C to 125°C 0°C to 125°C 0°C to 125°C 0°C to 125°C Package SOIC-14 SOIC-14 eTSSOP-16 eTSSOP-16 MLP-8 Packing Rails Tape and Reel Rails Tape and Reel Tape and Reel Block Diagram VDDQ 200k – VREFOUT VREFIN + VTTF……
