It has to stay within the high pressure limit and the discharge temperature limit. A R410a compressor is going to be rated for a very high pressure (400PSI is considered a "normal" high side pressure) and the recommended discharge temperature for any common compressor is less than 190F. In practice, because R290 and mixtures based on it don't superheat as much on compression, 140F and above condensing temperatures are easily achieved.
