FAN1655 - 3A DDR Bus Termination Regulator

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.

Features

  • Sinks and sources 2.1A continuous, 3A peak 0 to +125°C operating temperature range 5mA Buffered.
