    LED Matrix Using Shift Registers

    Check the datasheets of your shift registers and other ICs to see what the maximum operating frequency is.For example, a 74HC595 from Nexperia has a max quoted shift frequency of 100MHz.https://assets.nexperia.com/documents/data-sheet/74HC_HCT595.pdf

    5v Regulator

    Check the datasheet of the regulator that you use as it can vary and/or find one with the required output current.For example, you can find anything from 100mA in a TO-92 package, to 2A in TO-220, and various others in between, and probably more either side.
