The money is back up by US treasury bonds. When the government wants more cash, they issue new treasury bonds in order to print out more dollars. People buy US treasury bonds as a safe investment that they can cash in 10 years later at a certain % interest based on Federal Reserve interest rate.
If you keep printing out money faster than the economy grows, the money will depreciate. If the money depreciates too much, people lose a lot more money on treasury bonds. When people stop buying US treasury bonds, the government can't spend more/pay their bills.
