    Michael Day
    I agree that you will have a thermal problem with a TPS73601 SOT-23 package. I strongly recommend the DRB or DCQ package. You will need to make sure you have a lot of copper area in your ground plane to dissipate the heat. Another option is to spread out the heat by adding a resistor in series with the...

    Bill Stokes
    Hello Tancm, I don't see anything wrong with your schematic. Do you see any oscillations on either the input or output pins? I assume that the esr of the output capacitance has been verified to fall within the specified range. Sometimes when the traces to the input are more than a few inches in...

    Thanks for a reply. But my problem is i am very comfortable with linear regulator's(i don't have any experience with inductor). Actually my input voltage is varied from 10v to 42v.If i use this two regulators LM317KC(TO-220) & UA7805(TO-220)(even efficiency is low ) can i get the...

    Darwin Fernandez
    Hi Smitha, The thermal data can be found on page 3 of the datasheet. For further help, TI's thermal calculator ( http://www.ti.com/adc/docs/midlevel.tsp?contentId=76735 ) features a drop down menu that allows you to choose the IC you want, and depending on the your power requirements, suggests...

    HI, In my circuit , required output is 5V,150mA.My input voltage is 10v-42v. I plan to use LM317KC(TO-220) & UA7805(TO-220) . Can you please comment about this one or otherwise tell me some other suggestions. Thanks , B.stalin.

  • Forum Post: Re: How to know the power dissipation of the chip TPS73718

    Michael Day
    The maximum amount of power the IC can dissipate while still keeping the junction temperature below the absolute maximum rated junction temperature is a function of the ambient temperature and the thermal characteristics of both the package and your final PWB. The datasheet's "Power Dissipation"...
