  • 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 be…

  • TPS7A39: Driven by TPS65131 and the output is 0V

    Part Number: TPS7A39 Other Parts Discussed in Thread: TPS65131 Tool/software: Hello E2E Experts, Good day. I have used TPS65131 to generate +14V and -14V and used TPS7A39 to step down the output voltage to +12V and -12V respectively. Whenever a load…

  • 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 max output…

  • 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: Parallel output

    TI Thinks Resolved
    Part Number: TPS7A39 Other Parts Discussed in Thread: TPS7A33 hi sir that the TPS7A39 is a good device, but the current output is small could I use the Twice Tpas7a39 to double the output current? need +300mA thanks
