• LT3094 Spice Model Problem

    I'm trying to build a +/-16.5V power supply using either two LT8364 (which I already have) or one LT8582 and a pair of LT3045-1 / LT3094 to post-regulate the output of the DC/DC converters. As I'm trying to make use of the VIOC feature, I'd like to…

  • Can you connect LT3045 and LT3094 to create floating supply?


    I want to create a floating supply for my chip. I don't care a lot about absolute voltages as long as differential voltage is accurate and low noise. I see that capacitance on SET pin determines the output noise. Can I combine them as follow (see…

  • LT3094 Design Files


    I was wondering if anyone else has had this problem? I'm trying to view the design files in Altium for LT3094 (I'm aware they were designed in Orcad). I had successfully imported the design files for LT3045 but for LT3094, it keeps showing up blank…

  • LT3094: Input voltage effect on PSSR


    I'm using LT3094 in my one of the design.

    I observed that the dropout voltage is given as 235mV in datasheet. As well as there is a graph which provides the input voltage reference formula as Vin = Vout - 2.3V.

    So what is this about ?

    Can anyone…

  • SCP-LT3094-EVALZ layout so far to right of board on purpose?

    The SCP-LT3094-EVALZ has a long strip of copper between the input cap and the connector. Is there a reason for this? I'd like to make it a little more compact. Do I need to copy that in my final design?

  • RE: LT3094 LTspice simulation for -2.5 V


    The answer might be too late for Tim, but others might face a similar problem.

    If you change the output voltage by changing RSET, you also have to adjust the voltage divider from OUT to PGFB. If you don't do that, the startup circuit may try to quickly…

  • LT3094 unknown output


    I'm currently having an output issue that I hope someone can shed some light on.

    I have the LT3094 connected with the following:

    GND: pins 6 (ILIM), 9 (GND)
    VIN (@ -15V): pins 1 (IN), 2 (IN), 3 (EN/UV), 5 (PGFB), and 13 (Exposed Pad)
    PG: NC (floating…

  • LT3094 does not start correctly


    I am having issues with the start-up of the LT3094 negative LDO. 

    The LDO is used to generates -1.8V voltage from a -3.3V voltage, as shown in the schematic below: 

    Most of the time, the LDO will start correcly. But from time to time, the LDO output…

  • LT3045(-1) and LT3094 - can those work with >15V output (but no more than absolute rating of 16V)?


    From what I see in datasheet of LT3045/LT3045-1/LT3094 output voltage is up to 15V. Absolute maximum rating is 16V on any of pin (OUT, OUTS). In my application I need slightly higher voltage, ideally 16V, but still do not want to stress device to…
