    1. The problem statement, all variables and given/known data
    Tambient = 85degC, Vout = 1.05V, Iout = 600mA, 3x3 package with thetaJA = 40 deg. Celsius /W, Tjmax = 150 deg. Celsius...What is the max input voltage that the LDO can support while maintaining these conditions?


    2. Relevant equations



    3. The attempt at a solution
    Answer is one of the following answers
    a) 0 b) 3.2v c) 3.6 d)4.2v e) 4.56
