  • RE: AD7902+ADP7104-2.5V组合工作电流过大

    您好!ADP7104电路如下,

    我的电路如下:

  • ADP7104 and ADP151 input and output Capacitor

    Dear support,

    in my design I use ADP7104 and ADP151 linear regulator.

    In the figure 2 on pag.1 of the ADP7104 datasheet it reports an Electrolytic Capacitor, if I correctly understand,

    but on pag. 17 of the datasheet, it is written that ceramic…

  • RE: ADP3338 - 5V output with 0V input

    Hi grbk,

    Usually there is a diode in parallel with the pass element of an LDO, having a higher voltage on the output compared to the input by 0.3V would turn this on and probably destroy it. In the condition that the input is equal to 0V, the ADP3338…

  • 关于ADP7104-3.3

        用ADP7104-3.3做了一个稳压器,输入5V,输出3.3V。正常工作时候电流约为70mA。输出端并了三个电容:一个3528 10V 100uF的钽电容(靠近输出引脚)、一个0603 1uF 陶瓷电容、一个0603 1nF的陶瓷电容。

       现在有一个问题:有钽电容的时候,电源电流异常,有600mA之多,拿掉钽电容,电源电流正常。

       实在搞不懂原因是什么,麻烦各位坛友分析一下,感谢!

  • RE: voltage indicator

    It looks like you need a couple of comparators. You will have to set them up to control one or the other LED and or turn on a power supply for the LEDs. Let me know if you have specific questions about the parts.

    The ADMP356 may be useful

  • RE: AD9265-FMC reference design / Power Supply

    Based on the data published on the AD9265 FMC wiki page

    http://wiki.analog.com/resources/fpga/xilinx/fmc/ad9265

    The power consumption from the 12V rail should be <600mA as the ADP7104 is limited to 500mA and the other additional load is an LED. I doubt…

  • RE: ADP7104没电压输出,ADP7118输出不正常

    谢谢,问题找到了,ADP7118第4脚是要接到VOUT。

                                     ADP7104的第7脚要悬空,或接地。

  • RE: EVAL-AD7687-PMDZ with Arduino

    I have been testing the board and have seen that Vout of the ADP7104 is 1.8V. This is the voltage fed into the AD7678 which works from 2.5V-5V, so it seems like there is a problem there. Can anyone confirm please.
