    Roberts RD60 DB radio. Looking for some help Identify Component IC

    Hello. Im strugling to find a component.
    It is a DB radio, Input Voltage is 7.5v 800mA.

    The Component in question is 5 pin Sot-23 labeled as L1AH

    It takes 7.7 Vin then sends 5.5V to the gate of 358 transistor/MOSFET ic.

    358 takes 7.7v and outputs 5.5v same as gate Volage. NOTE if radio is off
    Gate pin is 7.7Voltage but transistor does not output any voltage.

    I have made schematics to best of my abilities, but im horrible at it the only Real Values are Voltages. and resistors.
    Appreciate any help.
    There should be images....

    This is a website with a reasonable amount of schematics.

    Just wondering if any of them matches my schematics.

      update : finally identified both the radio and ic: That's Roberts RD60 and the IC in question is XC6366B103MR. (marked as ic11 in circuit diagram) Datasheet https://cdn.badcaps-static.com/pdfs/...35bd38ce6d.pdf

      service manual for radio : part1- https://www.eevblog.com/forum/repair...92crc7ahpa4d12

      Part2 - https://www.eevblog.com/forum/repair...92crc7ahpa4d12

      Solved.
