  • TPS7A39: TPS7A39 to power 250mA load

    Part Number: TPS7A39 Tool/software: Hi, I am trying to use this TPS7A39 LDO voltage regulator for my design to power 250mA load. The first page on this datasheet it shows 150mA is the output current but in Electrical Characteristics table it shows current…

  • TPS7A39: External reference for TPS7A39

    Part Number: TPS7A39 Tool/software: Hello, We are planning to use an LDO TPS7A3901DSCT in our new design. We want to use an external precise reference instead of an internal reference. As we understand from the datasheet the external reference could…

  • TPS7A39: TPS7A39

    TI Thinks Resolved
    Part Number: TPS7A39 Tool/software: Ti Team, Planning to use TPS7A39 dual regulator.We need +5V at OUTP (pin10) and -5V at OUTN (Pin 6). Below is the questions: 1.Do I need to give +12V @INP (Pin 1) and -12V @INN(Pin 5) ? 2.If I give +12V @INP…

  • TPS7A39: TPS7A39 Simulation fails to converge when loaded

    Part Number: TPS7A39 I have put together a simple bipolar power supply base on the application notes in the TPS7A39 datasheet. The PSpice simulation works fine as long as the output is unloaded, but I would like to add components to the output to see…

  • TPS7A39: Questions of TPS7A39

    TI Thinks Resolved
    Part Number: TPS7A39 Dear Team, Do we have suitable solution can replace TPS7A3901DSCR? because lead time of this one is too long...(We need supply better than this one) Many Thanks, Jimmy

  • TPS7A39: Only negative voltage needed.

    Resolved
    Part Number: TPS7A39 Tool/software: Hi TI, I only need negative voltage output. What should I do with OUTP and FPB pins? Can I leave them floating? Are there any better options than TPS7A39 to provide -0.2V voltage? TPS72301 is not an option since…
