    What is this component marked G75LL on it? (U15) from a KW-M56BT audio system

    Hello,

    This audio system does not turn on and I managed to see that this component heats up when powered.
    Anyone knows what this component is?

    I show SMD marking G75xx as SGM2203-3.3 It is an LDO 3.3V 150mA in SOT-89 package, pinout GND, IN, OUT.

        Thank you! Is there a way to find this kind of information or is this your knowledge?

          I Startpage searched but with just the main numbers like "G75" - not the manufacturing plant info. An entire marking code is rarely listed, but the root part is.
          The IC does not have much heatsinking so it will easily run hot. If it has 3.3V output then I would check other power supply voltages.

            I went to Mouser out of Texas.. They are pretty big.. I have an account there.. Looks like Rewire did all the work I plugged in his numbers and description... https://www.mouser.com/c/?q=LDO%203....%20in%20SOT-89
            This is what I plugged in.. LDO 3.3V 150mA in SOT-89

            Redwire to the rescue 👍

            You can buy one piece of anything there, Give them a call...Rea Nice Peep's.
