FAN1655

3A DDR Bus Termination Regulator

Description

Features

The FAN1655 is

low-cost bi-directional LDO

■ Sinks and sources 2.1A continuous, 3A peak

■ 0 to +125°C operating temperature range

■ 5mA Buffered VREFOUT = VDDQ/2

■ Load regulation: VTT = VREFOUT ± 40mV

■ On-chip thermal limiting

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 appli-

cations. Load regulation meets the JEDEC spec, VTT =

VREFOUT ± 40mV.

■ Low Cost SO-14, Power-Enhanced eTSSOP or

8-pin 5x6mm MLP packages

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.

■ Low-Current Shutdown Mode

■ Output Short Circuit Protection

Applications

■ DDR Terminator VTT supply

The FAN1655 regulator is available in a power-enhanced

eTSSOP™-16, standard SOIC-14, and an 8-Lead MLP

package.
