Hot-selling and scarce FAN1654MTFX 1.5A LDO, DDR Bus Termination Regulator TSSOP16 spot stock
FAN1654MTFX 1.5A LDO, DDR Bus Termination Regulator TSSOP16 spot stock
Product Descriptions
The FAN1654 is a low-cost bi-directional LDO specifically designed for terminating DDR memory bus. It can both sink and source up to 1A continuous, 1.5A peak, providing enough current for most DDR applications. Load regulation meets the JEDEC spec, VTT = (VDDQ/2) ± 40mV.
The FAN1654 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 FAN1654 into a low power mode for laptop computer applications.
The FAN1654 regulator is available in a power-enhanced eTSSOP™-16 package, and the standard SOIC-14.
