7905接法參考圖:要知道7905的接法，首先當然是7905的管腳圖了，然后還有7905的應用電路。

*Required if regulator is separated from filter capacitor by more than 3×. For value given, capacitor must be solid tantalum. 25 mF aluminum electrolytic may be substituted.2Required for stability. For value given, capacitor must be solid tantalum. 25 mF aluminum electrolytic may be substituted. Values given may be increased without limit.For output capacitance in excess of 100 mF, a high current diode from input to output (1N4001, etc.) will protect the regulator from momentary input shorts.
