The newly-reinstated presidential proclamation says (Sec 3(b)) says
The suspension of entry pursuant to section 2 of this proclamation
shall not apply to:
(i) any lawful permanent resident of the United States;
The State department also lists exceptions to the travel ban on 8 countries, identifying those who "will not be subject to any travel restrictions listed in the Proclamation"
d) Any lawful permanent resident (LPR) of the United States;
Requesting / receiving a passport (or renewed passport) from your current country of citizenship does not invalidate your permanent resident status. Additionally, State says
No visas will be revoked pursuant to the Proclamation. Individuals
subject to the Proclamation who possess a valid visa or valid travel
document generally will be permitted to travel to the United States,
irrespective of when the visa was issued.
If you stay out of the country too long, that could cause a problem. If you plan to stay away more than a year, you have to first apply for a reentry permit.
This is the current state of the law, which is subject to change.
