• VIOC-Pin at the LT3094

    Hello,

    I have a question about the VIOC-Pin at the LT3094. Currently I am using the TPS65131 from Texas Instruments as a DC-DC-Converter. I have connected the LT3094 as a post-regulator at the negative output of the DC-DC-Converter. The positive output…

  • 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…

  • LT3094 Design Files

    Hi,

    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 unknown output

    Hi,

    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 thermal pad connection

    Hi, 

    We are using LT3094 to generate -5v 20ma from - 12v. 

    We made an error on the pcb that the thermal pad is floating instead of connected to input.

    Meanwhile we got - 5v at the output.

    Is there any performance degradation in this case? 

    Thanks. 

  • LT3094: Input voltage effect on PSSR

    Hi,

    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…

  • LT3094 does not start correctly

    Hi,

    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…

  • RE: LT3094 LTspice simulation for -2.5 V

    Hi,

    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…

  • LT3045 and LT3094 on one PCB

    Hi,

    The recommended PCB designs for LT3045 and LT3094 are presented in the form of two separate PCBs. In my project I would like to place both regulators on one board. My question concerns the GND planes on layers L2 and L3. Should the planes on each…

  • Any special precautions using LT3045 LT3094 as tracking regulators?

    Would like to use an LT3045 and LT3094 as tracking linear post-regulators to generate +/-3-6V supplies (that track eachother) - with a high-speed opamp (e.g. AD8610 or AD4625-1) in the feedback loop. Are there any special precautions in doing so?
