I am building an voltage source with an ADP150.

According the datasheet I need to use capacitors

with a low ESR for the best results. Ok, SMD is

not my favorite due all those datasheets. I can

find the X7R model but can someone tell me

which type…

I have the following LDO circuit with an equivalent DC and Pulse load.

With switch S1 closed the output at VDD shows >10mV of voltage drop during the pulse load .

The VDD output shows very little voltage drop with S1 open - see waveforms below.

Ho…

Hi,

Anyway, from the BF52x datasheet…

我详细地看一下ADP150的datasheet，根据噪声频谱图计算出来的噪声和手册给出的不太对。

手册给出10-100kHZ的噪声是9uV，但我根据下图计算红色框内的噪声就已经超出9uV了。

[0.03*0.03*(100K-10)]^0.5=9.48uV

两者值相差较大不知道是我计算方法有问题还是手册标注有问题。

请问使用ADP150芯片datasheet所给的典型电路能否驱动白光led（led的驱动输入为：3.0～3.2V  20mA）

寻找一款和ADP150类似的超低噪声，但是电流为300mA的LDO，麻烦推荐一下。谢谢

Looking for an ultra-low noise similar to the ADP150, but with a current of 300mA LDO, please recommend it.

Thank you

You are still using the standard 7805 to get a stable 5V output?

Well you need 7V (minimum)  Input Voltage for the 7805

Let say we need 100mA Output Current.

Which efficiency you will get from the 7805 versus an LDO like the ADP150?

Tip: Datasheet…

I'm looking at using the AD9548 in a design and I've been investigating power supply requirements. I've noticed that the ADP150 linear regulator is used to supply the 1.8V DVDD Supply. The ADP150 is specified to deliver 150 mA max current, yet the AD9548…
