Dear Sir/Madam,
As my limited knowledge, I only know the voltage divider, regulator (like LM780x) or adding a resistor between the power source and output to lower the voltage pass through the device. What are the advantage and disadvantage to these three methods?
I think adding a resistor is the worst solution because it wastes the power from the resistor, am I right?
Best regards,
Kelvin.
