Hi,
I was planning to use LM317 as a current limiter to a transistorized audio amplifier that would limit the current to 500mA.It is understood that the current would be limited by adjusting the output voltage i.e. drop more or less voltage across the LM317 to regulate the current.
My query is if the input signal level is low would the LM317 provide more voltage to the amplifier to maintain the current?
If the speaker shorts or the speaker terminals short accidentally would it still keep providing the 500mA which would result in blowing off the power transistors?
