• ADM7170

    Hello,

    I would like to use the ADM7170 with a voltage divider as shown in fig. 55 in the data sheet. I'd plan to use a DAC on the bottom of the divider with a 1nF cap to filter the DAC output. Is this acceptable or could it cause stability issues?…

  • ADM7170 - Vout 1.2 V

    Hi,

    I'm planning to use the ADM7170 as 1.2 V voltage source. According to the datasheet ordering guide table (page 23/23), the adjustable models (ADM7170ACPZ-R7 & ADM7170ACPZ-R2) are listed with an output voltage of 1.2 V.

    As stated on page 16…

  • ADP5003 / ADM7170 design check

    I've been working on a power design using the ADP5003 and ADM7170.  I hope you will point out any flaws since I 've never done this before! Slight smile

    Topology: The design uses the adaptive mode of the 5003 where the buck drives the LDO, converting 5V to…

  • Load regulation of ADM7170

    Dear,

    I'm trying to simulate the load regulation of the ADM7170 to compare it with figure 4 of the ADM7170 user guide. However, the simulation result is showing a different result for V(out) in function of V(in), the curve in the user guide is going…

  • ADM7170, ADM7171, ADM7172 soft start

    Is the soft start cap used to bypass the reference?

    Is there a max SS cap I can use?

    The description says also that SS needs to be left open when not used, but could the SS pin be used also as a REF in or Track function to lower the output voltage?…

  • Power Dissipation of ADM7170, ADM7171 and ADM7172.

    The data sheets for the ADM7170, ADM7171 and the ADM7172 all list the same thermal resistances even though their rated currents are 0.5A, 1.0A and 2.0 respectively. How can this be so if their maximum junction temperatures are all the same?

  • 关于LDO芯片ADM7170使用的问题。

    我想要使用ADM7170实现如下功能,输入电源电压+5V,输出电压+4.6V。查询ADM7170的手册使用其可调输出电压的参考电路设计,输出电压维Vout=1.2V*(1+R1/R2)。可是实际调试结果始终是输出5V电压,请问是什么原因呢?
