    Thread Summary
    
                The user inquired about the absolute maximum rating of the Vout pin, especially in cases where Vin is less than Vout. The support engineer provided curve trace graphs showing the internal circuit trips at around 0.5V difference between Vout and other pins, recommending Vout-Vin < 0.5V. The engineer also suggested adding external ESD protection if needed.

    Hi , 
    

    

    could you please let me know the Absolutist Maximum rating of  Vout pin .
    

    I would like to know this because there are case when the input falls below the Vout and  Vin < Vout (Capacitor).
    

    

    Thanking you 
    

    With best regards and wishes
