EM5049

2A Sink/Source Bus Termination Regulator

General Description

The EM5049 performs ultra low drop voltage

and fast response linear regulator specifically

designed to provide termination voltage for DDR

memory system. This device works with dual

supplies, a control input for the control circuitry

and a power input for providing current to output

and designed to source/sink up to 2A output

current. Output voltage is regulated to track the 1/2

reference voltage within 15mV variation.

The other features include soft start, current

limit protection, Power-On-Reset function, and

over temperature protection. The EM5049 is

available in DFN3X3 package.
