    Jayakumara,

    Below please find the answer to your questions:

    1. Typical Power, (Pd typ)

    Power depends on the voltage and the current dissipation within the IC, P=V*I. Thus, you need to provide the conditions before the power may me calculated; under quiescent conditions, IQ, (no output current) and supply voltage of Vs=5V;  P=Vs*IQ=5V*0.8uA=0.4uW

    2. Maximum Power (Pd max)

    The maximum power dissipation will occur under the max rated supply voltage and the max output current, Isc (short-circuit current); Pmax=7V*10mA=70mW

    3. Thermal Resistance Junction to Board (Theta JB)

    Theta JB is a function of the board itself - a dissipative surface area in contact with IC package

    4. Thermal Resistance Junction to Case (Theta JC);  Theta JC = 162.1 [deg C/W]

    5. Weight:   5.7 [mg]
