weitgehend der Vorgabe von Karl-Heinz Kübbeler mit folgenden Unterschieden: Als low drop Regler kommt der LP2950L5.0 zum Einsatz. Er kann 100mA liefern, mehr sollte man einer 9V-Batterie auch nicht abverlangen. Er hat den Vorteil, dass er schon mit Kondensatoren ab 1uF am Ausgang schwingungsfrei arbeitet. Bei
