LDO - Recommend replacement LDOs for 3.3V to 1.9V @ 1.9A, 3.3V to 1.1V +/-1.5% @ 1A and 1.8V to 0.9V @ 700mA for DD2

Question/Problem:

Recommend replacement LDOs for 3.3V to 1.9V @ 1.9A, 3.3V to 1.1V +/-1.5% @ 1A and 1.8V to 0.9V @ 700mA for DD2

Answer:

TPS75801, TPS74301 and TPS51100 are the only choices due to power dissipation, tight tolerance and DDR requirements.  But, need addt'l rails for TPS74301 and TPS51100.
