    @nischo: Welcome to Robotics India!!

    You should use a 7805 based regulated power supply for your 8051. The circuit should be like:

    The correct terminal by-pass capacitors for 7805 should be:
    C1= 0.33uFd. + 100uFd
    C2= 1uFd tantalum
    C3= 0.01uFd (10nFd)
    C4= 0.1uFd (100nFd)

    The Vpp MUST be >8VDC

    Hi all,
    For 8051 you actually need 5v.Try this power supply this gives both 5v & 12v & if you don't want 12v then remove 12v part.Here is the circuit

    Redefine it your way!!!!
