  • RE: LM25119: Design is not able to regulate properly under load.

    Understood, so TI would propose how much of margin in regarde to UVLO must be lower than 15V. So 1,87-1.25 is proposing over 0.5V noise spectrum? This is a huge noise and could this even possible when the VIN pin is already coupled by a 100nF X7R capacitor…
