Fairchild Semiconductor has expanded its portfolio of DDR memory system power solutions with the release of the FAN1655 LDO regulator that can sink and source up to 3.1A peak current.

The FAN1655's voltage regulation is claimed to meet the JEDEC specification for DDR memory interface for PCs, graphics cards, embedded computing systems, computer peripheral data buffers, and other DDR memory or bus termination applications.

Available in an SOIC-14 (FAN1655M) or ETSSOP-16 (FAN1655MTF) package, the LDO regulator features Kelvin sensing, ensuring regulation of VTT to VDDQ/2 40mV to achieve the highest possible data bus bandwidth. Additionally, a buffered voltage reference output capable of 5mA is provided for SSTL-2 interface devices.

Other features include power-conserving shutdown control and protection of the VTT output against overload and short circuit conditions by on-chip thermal limiting. The FAN1655 is fully specified from 0C to 125C temperature range and is guaranteed to be functional from a -40C to 125C temperature range.
