how to select an LDO regulator to get 3.3 v 200 mA of output from 5v and 250 mA of Input?
The regulator output current range is from 0 to 200mA. So you can use it for a 200mA max load. 160mA is within range of 0 and 200mA.

The regulator output voltage range can be set between Vfb and 5.5-Vdo. Since 3.3V is included in the range, you can set it to output 3.3V.

Your previous question already covers that the regulator can have 3.3V output with 5V input quite easily because the difference is much larger than minimum required.
