• ADP7182 runs out of current

    Problem with ADP7182.

    It works well with no load but runs out of current as soon as I place a small load ( 3mA). Load increases the overall current consumption by over 50 mA.

    The regulator does not oscillate, with stronger load, its current limiting fearture…

  • ADP7182 Adjustable Not Allowing -1.2V output

    I've wired the Adj pin directly to Vout to produce a -1.22V output with the Adjustable version. -5.5Vin and -1.2Vout. Unfortunately I'm getting -5V out. I've checked the part case lettering and it appears to be correct for the adjustable version so why…

  • ADP7182 輸出調整疑問

    您好!

    目前使用ADP7182希望從-25V轉成-1.8V, 調整adj分壓電阻為60.4KOhm 與 110KOhm後僅能得到-2.5V. 請問有其他的建議可以達到期望的輸出值嗎? 謝謝

  • Slow rise time application with ADP7182

    Hi


    I would like to have a very slow rise-up time by ADP7182.

    It’s about 5msec @ - 5V, as slower.

    Could you tell us if there is any good way?

    Regards

  • ADP7182 Noise reduction question in datasheet

    Hello all,

    first time poster here, so I am not sure if this ends in the right forum:

    I am working with some poer regulators: LDO type, positive and negative:

    ADP7118 and ADP7182 in SOT23-5 Package, just for some information. Adjustable versions

    Now…

  • ADP7182 和 ADP7142 型号和输出电压的关系？

    ADP7182 和 ADP7142 型号和输出电压的关系？

    最近用了以上两款LDO，型号分别如下，输出电压写的分别为-5V和5V。

            首先，我想问一下这个输出电压是固定输出电压吗？还是内部参考电压？因为在实际使用时的现象和手册写的不太一致。

            在实际使用中，7142接成可调输出，R1=R2=10kΩ，测试输出端电压为10V，所以这个型号是可调输出？5V是内部参考电压？

            但是7182同样接成可调输出，R1=R2=10kΩ，测试输出端电压只有1.2V，ADJ管脚的电压为R2的分压值0…

  • ADP7182采用固定输出对输入的要求

    1、ADP7182如果采用固定输出-5V的芯片，假设输入只有-5V，那固定输出是多少？

    2、可以长时间这样使用吗？

  • 在ADP7182中，如果要自动启动引脚怎么接？

    1、是采用如图所示，直接接到VIN吗？之间不用电阻之类的吗？

    2、手册中推荐的电容是有符号的，这里直接用无极性的会不会有问题？

    谢谢

  • adp5070数据手册中24页，ADP7182的设计如何理解

    ADI专家，您好！adp5070数据手册中的24页，设计正负15V电压，-15V采用了adp7182，电阻值的设计为什么跟adp7182数据手册中的说明不一致？
