Die oberen Angaben sind bei Verwendung eines neuen\/vollen 1,2V NiMH-Akku entstanden, bei einer Versorgung \u00fcber Batterie bzw. Netzteil oder auch h\u00f6heren Eingangsspannung ist der belastbare Bereich gr\u00f6\u00dfer, ehe die f\u00fcr mich relevanten 3,3V am Ausgang unterschritten werden. Ich muss dabei allerdings die Kirche im Dorf lassen, in der Regel versorge ich im Modellbau mit so einer Schaltung wei\u00dfe LEDs und Mikrocontroller, kaum \u00fcber 10-20mA Gesamtstromaufnahme, eher weniger. Die aktuellen Leuchtdioden sind schon bei ca. 1mA ausreichend hell, der Controller selber ist noch gen\u00fcgsamer. F\u00fcr meine Zwecke vollkommen OK, unten die Links zur Bezugsquelle.<\/p>\n<p>Fazit:<\/p>\n<p>F\u00fcr kleine Lasten absolut ausreichend, wenn ich mehrere hundert mA am Ausgang brauche, w\u00fcrde ich zu anderen L\u00f6sungen greifen! Im aktuellen Beispiel muss aber auch immer der Preis von ca. 0,6\u20ac\/Platine im Auge behalten werden!<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<!-- relpost-thumb-wrapper --><div class=\"relpost-thumb-wrapper\"><!-- filter-class --><div class=\"relpost-thumb-container\"><style>.relpost-block-single-image, .relpost-post-image { margin-bottom: 10px; }<\/style><h3>Related posts:<\/h3><div style=\"clear: both\"><\/div><div style=\"clear: both\"><\/div><!-- relpost-block-container --><div class=\"relpost-block-container relpost-block-column-layout\" style=\"--relposth-columns: 4;--relposth-columns_t: 3; --relposth-columns_m: 2\"><a href=\"https:\/\/www.michael-floessel.de\/mfblog\/personliche-nostalgie\/\"class=\"relpost-block-single\" ><div class=\"relpost-custom-block-single\"><div class=\"relpost-block-single-image rpt-lazyload\" aria-hidden=\"true\" role=\"img\" data-bg=\"https:\/\/www.michael-floessel.de\/mfblog\/wp-content\/uploads\/2026\/04\/the-joker-pic-4-michael-floessel.de_.jpg\" style=\"background: transparent no-repeat scroll 0% 0%; width: 1000px; height: 288px; aspect-ratio: 16\/9;\"><\/div><div class=\"relpost-block-single-text\"  style=\"height: 75px;font-family: Arial;  font-size: 12px;  color: rgb(237,201,23);\"><h4 class=\"relpost_card_title\">Pers\u00f6nliche Nostalgie<\/h4><\/div><\/div><\/a><a href=\"https:\/\/www.michael-floessel.de\/mfblog\/ein-tipp-zum-mehrfachen-ic-entfernen\/\"class=\"relpost-block-single\" ><div class=\"relpost-custom-block-single\"><div class=\"relpost-block-single-image rpt-lazyload\" aria-hidden=\"true\" role=\"img\" data-bg=\"https:\/\/www.michael-floessel.de\/mfblog\/wp-content\/uploads\/2026\/04\/the-joker-pic-4-michael-floessel.de_.jpg\" style=\"background: transparent no-repeat scroll 0% 0%; width: 1000px; height: 288px; aspect-ratio: 16\/9;\"><\/div><div class=\"relpost-block-single-text\"  style=\"height: 75px;font-family: Arial;  font-size: 12px;  color: rgb(237,201,23);\"><h4 class=\"relpost_card_title\">Ein Tipp zum mehrfachen IC entfernen<\/h4><\/div><\/div><\/a><a href=\"https:\/\/www.michael-floessel.de\/mfblog\/demo-softwinner-evb-a13\/\"class=\"relpost-block-single\" ><div class=\"relpost-custom-block-single\"><div class=\"relpost-block-single-image rpt-lazyload\" aria-hidden=\"true\" role=\"img\" data-bg=\"https:\/\/www.michael-floessel.de\/mfblog\/wp-content\/uploads\/2016\/01\/softwinnerevb_a13_header-1-1000x288.jpg\" style=\"background: transparent no-repeat scroll 0% 0%; width: 1000px; height: 288px; aspect-ratio: 16\/9;\"><\/div><div class=\"relpost-block-single-text\"  style=\"height: 75px;font-family: Arial;  font-size: 12px;  color: rgb(237,201,23);\"><h4 class=\"relpost_card_title\">Demo, Softwinner Evb A13...<\/h4><\/div><\/div><\/a><a href=\"https:\/\/www.michael-floessel.de\/mfblog\/fotostrecke-zur-bombensprengung-in-duisburg-waz-de\/\"class=\"relpost-block-single\" ><div class=\"relpost-custom-block-single\"><div class=\"relpost-block-single-image rpt-lazyload\" aria-hidden=\"true\" role=\"img\" data-bg=\"https:\/\/www.michael-floessel.de\/mfblog\/wp-content\/uploads\/2026\/04\/the-joker-pic-4-michael-floessel.de_.jpg\" style=\"background: transparent no-repeat scroll 0% 0%; width: 1000px; height: 288px; aspect-ratio: 16\/9;\"><\/div><div class=\"relpost-block-single-text\"  style=\"height: 75px;font-family: Arial;  font-size: 12px;  color: rgb(237,201,23);\"><h4 class=\"relpost_card_title\">Fotostrecke zur Bombensprengung in Duisburg | WAZ.de<\/h4><\/div><\/div><\/a><\/div><!-- close relpost-block-container --><div style=\"clear: both\"><\/div><\/div><!-- close filter class --><\/div><!-- close relpost-thumb-wrapper -->","protected":false},"excerpt":{"rendered":"<p>Das Problem: Versorgt werden kann oder muss die Elektronik aus einem 1,2V Akku oder einer 1,5V Batterie, 3V m\u00fcssen aber mindestens f\u00fcr die Schaltung vorhanden sein.
