  • LP2985-N: Vout vs temp and temp drift

    TI Thinks Resolved
    Part Number: LP2985-N Hi Team, Here is a question from customer. Customer use LP2985-3.3V as Vref for high accurate ADC and they find Vout changes with temp and different part changes at different amplitude. So customer hope to get help on below: 1. Vout…

  • LP2985-N: Battery and USB power circuit

    TI Thinks Resolved
    Part Number: LP2985-N Hi to all, I built a circuit to power a 3.3v power source using both battery and/or USB cable. The battery section of my circuit seems to work fine. the USB section is using a LP2985-33 and I cannot get 3.3v at the output. instead…

  • RE: LP2985: LP2985 Disable issue, Vout is 2.0 when disabled.

    HI Andrew, I would recommend testing with a pull-down at ENABLE to see if it helps. If you are using LP2985-N then it does not have an output pull-down, the one I showed was the newer version LP2985 (non-N): https://www.ti.com/lit/ds/symlink/lp2985.pd…

  • LP2985-N: Enable threshold

    TI Thinks Resolved
    Part Number: LP2985-N Hi, In datasheet, 1.6V is the minimum to enable and 0.15V is the maximum to disable. Questions: What is the accuracy for this threshold value? What happen to Vout if Ven falls in between 0.15V and 1.6V? Can I have the Ven vs Vout…
