FAQ

手册上没发现相关描述，个人认为悬空肯定是可以的，不知道接地是不是也可以？两者方式哪种更好？

### Q

I am using an ADP1741 to step down 2.0V to 1.8V. I need output current of 2A +

My proposal is to have 2 x ADP1741s in parallel. Will this work?

### A

You could use ballast resistors to ensure that the LDOs will share.  Size the
ballast…

• ### how to understand dropout voltage in LDO datasheet?

Hello,

Recently I have a problem about dropout voltage. I need ADP1741 to output 1.8V,the dropout voltage from ADP1741 datasheet is 280mV max,Iout=2A. Does it mean my Vin mustnot exeed 2.08V？so I cannot understand real mean about "dropout voltage".How…

• ### RE: ADP1741ACPZ-R7 dropout voltage

Hi Belenie,

You could use a headroom below 400mV but that would depend on how much noise is going in to the ADP1741 and how much noise is allowed to come out of it. With low headroom the effective drain to source voltage of the pass element is equal…

• ### RE: getting consistent output from ADIS 16375

How are things going?  We have had to delay our FAQ on a linear regulator design for the ADIS16375, but I wanted to offer some starting points, in case you are going to do this yourself:

• ### LDO关键的指标和定义，您了解多少

输入电压范围：LDO的输入电压范围决定了最低的可用输入电源电压。指标可能提供宽的输入电压范围，但最低输入电压必须超过压降加上想要的输出电压值。例如，150mV的压降对于稳定的2.8V输出来说意味着输入电压必须大于2.95V。如果输入电压低于2.95V，输出电压将低于2.8V。

接地（静态）电流：静态电流lq就是输入电流lIN和负载电流IOUT之间的差值…

• ### 最新方案文档推荐——医疗X射线成像解决方案

医疗X射线成像检查的目的是识别病人身体中的异常情况或将病人归类为健康人群，同时最大程度地降低辐射影响。数字X射线(DR)和计算机断层扫描(CT)是最常用的X射线成像技术和应用。

医疗X射线成像原理和典型架构

DR和CT的基本工作原理相同：X射线束穿过人体，一部分X射线由内部结构吸收或散射，余下的X射线图案传输到检测器，用于电路和计算机进行记录或进一步处理。

DR检测器：DR检测器包括闪烁晶体层、TFT面板、模拟数据采集系统和数字处理系统。闪烁晶体层将X射线光子转换为可见光子，TFT面板将可见光子转换为电子…
