• LT3093 Pin 13 and 1 connected in the chip?

    I have soldered an LT3093 to a breakout PCB and I'm trying to determine that Pin 13 (IN, the pad on the bottom) has made a good connection.  I thought I could use a multimeter to see that the resistance between Pin 1 (also IN) and the breakout PCB pad…

  • LT3093 burns after leaving on overnight

    I am using LT3093 as a negative voltage regulator in the following configuration:

    Input is -12V and output set by R8 is -9V.

    Leaving the board on overnight, I see the device is completely burnt and its PCB pads were damaged too.

    I also use LT3045 on the…

  • How to use the LT3093 with BJT to implement higher current output

    I have a question.

    LT3042 have two type of application circuits that be used on the BJT of NPN and PNP to implement higher current output.
    But I can't find any similar applications of LT3093 in datasheet.

    Do you know the reason?

    Wait for your kindly…

  • 关于LT3093设计文件打不开的问题

    您好,

      我从ADI的官网上下了LT3093的评估板文件“DC2952A - Design Files”,但其中“DC2952A-1.pcb”文件使用Altium Designer 18,Allegro等软件无法打开,使用Import也无法导入。

      所以我想问下,应该如何打开.pcb格式的评估板文件呢?直接看gerber文件不太习惯。

      期待您的解答,感谢~

    电源树

    CN-0531电源树如图2所示,包括 LT3471 升压/反相转换器,其后是 LT3042 (正)和 LT3093 (负)超低噪声、超高PSRR线性稳压器。

    LT3471允许电路从开发平台板提供的3.3 V或5 V单电源供电。输出电压设置为±8 V,然后由LT3042和LT3093调节至±7.5 V。在LT3471的1.2 MHz开关频率下,LT3042和LT3093分别提供出色的80 dB和75 dB PSRR,确保DAC输出端的开关馈通最小。

  • RE: PSRR of LTC1563

    Hello Fdelaram

    Thank you very much for your reply. It seems that the noise of the switching power supply is visible in the output of the LTC1563. I try to recommend LT3042 and LT3093 supplying to LTC1563. 

    Regards,

  • RE: Need help with ADuCM355 power supply bypassing capacitors.

    Even batteries can be appearing noisy if you want to make some very precise measurements with your end product. 

    For some chmeical sensing that might be quickly the case.

    Luckily there are LDOs like LT3042 or LT3093, whose noise levels are even lower than…

  • 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…

  • Why do the new ultra low noise regulators have different pinning with positive and negative voltages?

    Hi,

    there are the LT3045, LT3045-1, LT3049, LT3093 with the first two being positive voltage regulators and the latter two negative voltage ones.

    At least the LT3045-1 and the LT3049 have comparable specifications and also comparable pin functions.
