Bus lines 6, 11 and the C-lines run between the University and the central Bus station „Albertstraße“ at least every 20 minutes (every half hour at night). Walking takes about 30 minutes.
If you are planning to visit other cities or are going from/to Munich by train, the nation-wide ticket for all local transport (D-Ticket, Euro 49/calendar month) might be an option. It will cover all public transport (e.g., busses) and local trains within Germany (e.g., Nuremberg-Regensburg or Munich-Regensburg) but not long distance trains (e.g., Frankfurt-Regensburg, i.e., IC/EC or ICE). This ticket is only available as a subscription that can easily be cancelled directly after having booked the online ticket for September at the above link.
