    Please can somebody send me any useful links in order to teach myself about Op amp controlled linear voltage regulators ? I must design and simulate an op amp linear regulator circuit using a 5v zener diode as a reference voltage, with feedback from sensing resistors, to maintain a constant output voltage. I am having great difficulty in designing this and need to learn a lot more about op amp controlled linear regulators to continue my studies.

    Any help will be greatly appreciated,
    Thankyou

    It is easy to improve the performance of the circuits that Eric and Jony linked to by moving the Zener and its current limiting resistor so that its source is the regulated output voltage. This way, the dynamic impedance of the Zener doesn't add ripple to the output...
