Dear Sir/Madam,
I have a question for your LDO ADP7102.
If I do not put 100kohm RPG resister as your Fig.62 page-17 data sheet, then is the output voltage larger than designed value as formula VOUT=1.22 V{1+(R1/R2)}?
We tried to use your ADP7102 a…
Hi Sridhar,
The output accuracy of ADP3303 and ADP7102 are about the same. The ADP7102 has lower noise: by keeping the LDO error amplifier in unity gain and setting the reference voltage equal to the output voltage, the ADP7102 fixed output versions…
如图：ADP7102的输入电压15V，同时EN/UVLO与Vin短接以保证芯片上电自启动， ADP7102的输出Vout通过调配电阻设置为12V，Vout用来给几个运放芯片供电，所以负载电流对芯片毫无压力。 Vin和Vout芯片引脚边上各自接了一个2.2uf对地电容，电容的电介质为X7R。
问题来了， ADP7102有时输出异常，为-0.8V（or +0.8V，抱歉有点记不清了），有时则输出正常的+11.98V。 以为芯片坏了，换了2颗新的ADP7102也是一样情况。 后来发现了一个非常奇怪的规律…
我觉得加个100k电阻会好一些
I took a look at the ADP7102 it looks like a great product! In this particular case, our primary goal was to power a digital sensor with a supply that reaches 3.3V in less than 100us, so the 800us start-up time in the ADP7102 will not meet this objective…
ADP7102的详细中文使用手册哪位先生有啊？谢谢了啊！
I would like to use an ADR3450 in order to build a 300mA, high precision, 5V voltage regulator.How can use it, if the maximun input voltage is really 5.5V (6V in absolute maximum ratings)?
The ADR3450 would need an input voltage of 5.2 to 5…
ADIsimPower is a very nice tool.. a real time saver. However I noticed an error in the tool for the ADP2102.
Using parameters for input voltage of +12V the tool specified an input capacitor rated at 6.3V. Either that, or C1 and C2 in the diagram below…
Hi Andy,
We recommend the ADP151, which is a higher current version of the ADP150:

Also, the linear team has just introduced the 300mA ADP7102 & 500mA ADP7104…
Note 12V could not supply to this due to that eval board SDP-B was broken also my PC/ USB BUS.......
ADP7102 and FDN335/FET can accept 12V no problem.
J2 on ADUX1020 MCM board was also offed=opened.
Please advice us !!!
Thanks KAOS
