    Hello
    

    https://www.analog.com/en/design-notes/constantpower-source.html
    

    In the article at the above URL, it was a 100mW constant power circuit.
    I want to design a 30W circuit.
    By the way, the circuits in the article are controlled by an error amplifier and a transistor, except for the MAX4210E. 
    I think the configuration of this error amplifier and transistor is similar to the configuration of LDO. So, can we substitute 
    LT1058 or LT1084 for this part?

    Also, do you have any plans for LTSPICE modeling of the MAX4210E?
    

    Thanks
