• ADP2164 and ADP2164-1.8

    Hi,

    I am using one of regulator ADP2164 in my circuit to generate 1.8 V from 3.3 V input. unfortunately i mounted ADP2164ACPZ-1.8 instead of ADP2164APZ. As per my circuit i used feedback resistors to adjust and i mounted the which has fixed output voltage…

  • footprint of ADP1707ACPZ-1.8-R7

    I requested a footprint of ADP1707ACPZ-1.8-R7 from the request form.
    I waited. But I don't get a footprint yet.
    How should I do to get a footprint of ADP1707ACPZ-1.8-R7?

    Give my best regards.

  • LT1763-1.8 wrong output voltage

    Hello,

         I want to use the LT1763IS8-1.8 chip to convert +5V to 1.8V. The schematic and PCB are as follows, but in the actual circuit, the output of the 1-pin is measured by a multimeter to be 2.1V, and the +5V input is also reduced to 4.5V. Why, what should…

  • ADM7171ACPZ-1.8 output voltage abnormal uprise

    A ADM7171ACPZ-1.8  circuit is set to provide DRVDD power supply for AD9650 AD converter module. And the data coming out of the AD9650 is transferred to a XIlinx FPGA core.Before the FPGA core is connected to the AD module, the output of ADM7171A keeps…

  • LT1764-1.8 has the same input and output

    Hi,

        I design a 1.8V power supply module with LT1764-1.8, and the input voltage is 12V.

       The VIN pin and SHDN pin are connected together and they share a 10uF Capacitance.

       The OUT and SENSE  are connected together and they share a 10uF Capacitance.

       But…

  • BC857 as a 1.8 regulator transistor for adau1701

    Hello everybody, I have been making the schematic for my own 1701 board (yay yay). But since I am not an engineer I am awfully afraid of making any mistake. So I chose BC857 as a 1.8 regulator transistor since it is small and has a huge beta. It seems…

  • ADM7150ARDZ-1.8 produce 2.8V instead of 1.8V ??  WTF?

    Using several of these parts on a board.  6 out of 10 are producing 2.8V instead of 1.8V.

    Yes I have verified the correct part is installed.  Each of the circuits are identical except for the load.

    Need help ASAP!

  • ADP151ACPZ-1.8 exposed pad connection in adjustable output voltage operation mode

    Hi all!
    I want to get 3V output using ADP151ACPZ-1.8 in adjustable output voltage operation mode. 
    My schematic is:

    But I'm not sure about EPAD pin connection. Could I connect EPAD pin to PCB ground. Or I must connect it to GND pin  of ADP151?

  • LT1764-1.8 输出电压与输入相同

    使用LT1764-1.8设计一个输入12V输出1.8V的电源模块。VIN与SHDN相连,接输入12V,两者共用一个10uF去耦电容;VOUT与SENSE相连,两者共用1个10uF去耦电容。

    上电后VOUT的电压为12V,与输入相同,而不是1.8V。

    有哪些原因可能会造成这种问题?是否与PCB设计有关?

    谢谢!
