Fairchild Semiconductor International (San Jose, CA) has expanded its family of double data rate (DDR) interface power products by introducing a low-cost, low drop-out (LDO) regulator with bi-directional output that is capable of sourcing and sinking 1A. The FAN1654 is able to handle transient loads up to 1.5A. The FAN1654 is suitable for desktop and notebook PCs, graphic engine memory buffer bus termination, embedded computing systems, computer peripheral data buffers and other small DDR memory applications.
The FAN1654 features a shutdown control for turning off the device’s outputs, which reduces power consumption, as well as protection against overload and short-circuit conditions by on-chip thermal limiting. The FAN1654 is rated for operation over the required -40 to +125 degrees C temperature range. It is available in a power-enhanced, 16-lead, exposed-pad TSSOP package and a standard 14-lead SOIC. Both packages are supplied in either tube or tape-and-reel packing.
Available now, the FAN1654M is priced at $0.95 each in 1,000-piece volumes. Delivery is seven to eight weeks ARO.
