I try to generate 1.2V@800mA from TLV757P with VIN=1.8v. According to the datasheet, fig 14 and 15 shows in 3.3V and 5V VIN. What is the dropout when VIN=1.8V or how to estimate it?

Hi,
At 1.2VOUT, the TLV757 has an effective RDSON of 1.1-Ohm:
So at 800mA, the worst case drop would be 880mV which means that the TLV757 could not do this. However, the TPS746 can.
I hope this answers your question.
