Description
The FAN1655 is a low-cost bi-directional LDO specifically
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.
