Design the heatsink for the power transistor of a voltage regulator, keeping the heatsink cost minimal.The voltage regulator has an output voltage of 5 V and full load current of 500 mA. At full load, the regulator efficiency is 25 %, with the power transistor contributing to 45% of the power loss. The regulator is expected to operate at ambient temperature of between 20 °C and 40 °C. The heatsink temperature should not be more than 80 °C. Assume the cost of the heatsink is inversely proportional to the value of the thermal resistance θSA. The power transistor has the following parameters:θJC = 3 °C /WTJ,max = 150 °CDetermine the thermal resistances, θCS and θSA.
