A LM7805 ends with \u003cstrong\u003e“05”\u003c\/strong\u003e; thus, it outputs 5 volts. The \u003cstrong\u003e“78”\u003c\/strong\u003e part is just the convention that the chip makers use to denote the series of regulators that output positive voltage. The other series of regulators, the LM79XX, is the series that outputs negative voltage.
