• adp3338

    有一片型号为ADP3338 LDO,固定输出为3.3V,不上电点阻抗发现输入5V和输出3.3V对地都是300Ω左右,输入输出管脚之间阻抗只有6Ω,正常芯片有1.5K左右,关键是上电后芯片输出输入电压正常,不知道什么原因,求解惑。

  • ADP3338-5 dropout voltage

    Hi,ADI Expert

    I use the low cost LDO adp3338-5 as the digital power regulator for my design.but now i am confused with the one of its features.I quoted the feature here-- 'Ultralow dropout voltage: 190 mV (typ) @ 1 A'.In my design,i supply adp3338-5…

  • ADP3338: Thermal and overcurrent protections

    I´m using the ADP3338 LDO, and I´d like to clarify a question regarding thermal
    From my point of view the bigger the termal cooling area on the PCB the better
    (even in the LDO does not have to dissipate many power).
  • ADP3338 - 5V output with 0V input

    I'm designing a system for a car with two use cases. In normal operation, the system is powered by the 12V car battery, which is regulated to 5.6V by a buck-boost regulator and then to 5V by the ADP3338. When the system is outside of the car, however…

  • RE: ADV7341 I2C

    Hi Amnon,

    You replaced the ferrite beads with wire it improved matters. Instead of the wire, could you try connecting in an external bench power supply to see if that resolves your issue altogether? I have attached the BOM which includes the details…

  • RE: Recommended 1.8V regulator for 8 DDS chips

    Hi Prakash BJ,

    The AVDD and DVDD supply pins of the AD9959 draws a maximum of 325mA when all channels are turned on.

    The 800mA maximum output current of the ADM7160 can only supply up to two DDS chips.

    There are higher current output LDOs such as the…

  • RE: ADSP-21992 Booting Problem


    So, I tried to use a quick power supply (100 us startup time, 2x ADP3338 - the same, as on the ADI's Starter Kit) and the problem still remains. There is no change whether both the voltages are switched on simultaneously, VDD_EXT first and then VDD_INT…
