This is very bright and we get three different colors from the LEDs and with such brightness. Can you please explain the working of this circuit i.e. how would you manage to get three different lights from the single output and what sort of multiplexing device you use? Moreover, Can you please tell me the input power requirement of this circuit? pcb quote
I studied about the LE33CZ voltage regulator that it has a very low drop out voltage and moreover it has a very low quiescent current so what I think it does not create any problem if you will use the diode to offset the output voltage of this voltage regulator but just put a 2.2uF capacitor for the stability of the voltage regulator.
