schwingungsfrei arbeitet. Bei 10uF ist dies sicher gewährleistet. Die Anschlüsse sind zudem identisch mit dem 78L05. Um den Transistor BC548/547 (T3) , der nur 100mA Last verträgt zu ersetzen, ist der BC328 mit erlaubten 800mA eine gute Wahl. Die Drossel L1 entspricht der Standard-Beschaltung von Atmega’s, die auch
