schwach glimmen, von 160mA keine Spur. Um nun alle LEDs einfach dimmen zu können brauchst du einen LM317 im TO220 Gehäuse + dicken Kühlkörper (Wärmewiderstand < 10K/W). Dann brauchst du noch eine Gleichspannuung von ca. 20V. Den LM317 beschaltest du wie im Datenblatt mit variabler Ausgangsspannung von

unique requirements for a o voltage regulator that cannot be met by the industry stan- s dards like the LM340 or the LM317. These regulators use an : NPN Darlington pass transistor (Figure 1), and will be re- T ferred to in this document as NPN regulators. The demand e for higher performance is being met
>was spricht gegen den LM311? Es spricht nichts gegen den LM311, es gibt viele Möglichkeiten einen Oszillator zu realisieren. Nur es gibt Momente in einem Leben, da hat man keinen LM311 zur Hand und sucht eine Alternative
Hallo Gast, > Welchen OPV (2 mal LM311 ??) gegenwärtig verwende ich 2xB082 (NF-OPV DDR 1984), andere hab' ich momentan nicht vorrätig Besser wäre die Komination OPV mit hoher Grenzfrequenz + LM311, vielleicht sogar 2x LM311, aber
entsprechende in Wärme umgesetzte Verlustleistung am 7x09 beträgt demnach (15,4V - 9V) x 0,6A = 3,84W. Und dies pro Regler! Gruß Holger
jedoch anstatt +9; -9V zwei 12V Regler eingesetzt (also + & -); die 5 V habe ich weggelassen (folgt LM317...). Eingesetzt wird ein ERA-Trafo mit Sekundär 2 * 12V. Nun denn, er gibt ca. 14V raus; hinter dem Gleichrichter habe ich jedoch 19V DC!!! Wie kann das sein? Ich habe doch Udi / Uv ~ 0,9?!? Confused
genug und dieses Exemplar kommt damit nicht klar. Ich hatte ein ähnliches Phänomen: bei einem PIC16F84 schwingt der externe Quarz nicht richtig, bei fünf anderen überhaupt kein Problem.
Hallo, Was mir nun noch aufgefallen ist: In der Schaltung habe ich einen LM7805 zur Erzeugung der 5V eingebaut. Wenn ich diesen auf der 5V-Seite kurz kurzschließe funktioniert der AVR auch einwandfrei. Was kann da sein. Warum funktioniert das Programm ca. 1 bis 2 Sekunden
