Features

Sinks and sources 2.1A continuous, 3A peak to +125C operating temperature range 5mA Buffered VREFOUT = VDDQ/2 Load regulation: VTT = VREFOUT 40mV On-chip thermal limiting Low Cost SO-14, Power Enhanced eTSSOP 8-pin 5x6mm MLP packages Low-Current Shutdown Mode Output Short Circuit Protection

Description

The is a low-cost bi-directional LDO specifically designed for terminating DDR memory bus. It can both sink and source 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 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 eTSSOPTM-16 package, and the standard SOIC-14

Feedback for remote sense of the VTT voltage. Alternative input for direct control of VTTOUT and VREFOUT. Shutdown. This active low shutdown turns off both VTT and VREFOUT. This pin has an internal pull-down, and must be externally driven high for the to be on. Signal Ground. Buffered Voltage Reference Output. VDDQ Input. Attach this pin to the VDDQ supply to generate VTT and VREFOUT. No Internal Connection
