  • RE: TPS7A54: TPS7A54 parallel method and other LDO recommend

    Hi Hale, We have written 2 white papers and 1 software tool on paralleling LDO's using ballast resistors. We are in the process of adding more LDO's to the software tool, and we wish to update this year for the TPS7A52/3/4. You can easily parallel…

  • TPS7A74: 2 LDO in parallel to double output current...

    Part Number: TPS7A74 Other Parts Discussed in Thread: TPS7A57 , TPS7A54 , TPS7A53 Dear Sirs, May I use 2 LDOs in parallel to get a double output current? My customer wants to use 2pcs TPS7A7401 to do such design. Please help to advise. Thanks.

  • LP8733: Using LDOs in Parallel ?

    TI Thinks Resolved
    Part Number: LP8733 Other Parts Discussed in Thread: AM2434 , Considering using the DP87334 device, which is pre-configured for the Sitara AM2434 SoC. I do not want to have to program/configure it to modify the default settings if possible. The DP8733x…

  • RE: TPS7H1101A-SP: 2 LDO's In Parallel Stability/Bode Simulation

    Resolved
    Thanks Wade, promising results. I need to do an analysis of the pdn network between our loads and the bulk dcaps at ldo outputs to assess if the 500ns rise/fall time is reasonable approximation of our application. I'll follow up when i get that answer…

  • RE: TPS7A84A: Paralleling Multiple TPS7A84A Devices with adjustable operation(R divider)

    Hi Justin, Please ask if you have any questions on this topic at all. If you would like me to help design your parallel LDOs, I can do that if you provide me with your system requirements: Shown below is a representative schematic to parallel the TPS7A84A…

  • RE: TPS7A94: Paralleling for Higher Output Current and Lower Noise

    Hi Justin, Yes, chip resistors are fine. I usually start at 0805 or 0603. Depending on your ambient temperature and the power dissipation, you may be able to select an 0402. You need to review the derating curve in the resistor datasheet to verify you…
