    For LM317AMEP and LM317EMP: SOT-223-4 / DCY

    1. Junction Temperature Max (Tj Max)
       1.1) ABSMAX Operating Junction Temperature = 150 C
       1.2) MAX Operating Junction Temperature = 125 C

     2. Typical Power dissipation (Pd typ)
         2.1) Application Dependant : Pd=((Vin-Vout) x Iout)

    3. Maximum Power dissipation (Pd max)
       3.1) Theta(JA) Dependant

    4. Thermal Resistance Junction to Ambient (Theta JA)
        4.1) Theta JA-High K JEDEC 4-Layer (standard datasheet value) = 58.5 C/W

    5. Thermal Resistance Junction to Board (Theta JB)
       5.1) Theta JB (standard datasheet value) = 7.2 C/W

    6. Thermal Resistance Junction to Case (Theta JC)
       6.1)  Theta JC, top (standard datasheet value) = 39.6 C/W 

       Also:
       Psi JT (standard datasheet value) = 1.7 C/W
       Psi JB (standard datasheet value) = 7.1 C/W

    7. Weight
       7.1) Device Mass: 120.900000 mg
