LT3081 datasheet briefly mentions about the in built protection like reverse input & output voltage, thermal protection. But do we need to add any external protection circuit for LDO? for example reverse current protection diode between IN and OUT pin…

Looking for a way to provide a clean 300V DC (approx.) output from a rectified 320-330V DC (50Hz sawtooth ripple 10Vpp, from a full bridge rectifier.)

Can I use a LT3081, with 6Megohm SET resistor (appropriate voltage rating) - alternatively are there…

Hello

Now I'm working on development using the LT3081 and LT3090.

It is a simple circuit in which the input voltage to the SET pin of LT3081 and LT3090 is output to Vout (Vout = same to SET pin voltage).

I have something curious about my circuit now…

A customer essentially asks, "What is the easiest way to shutdown the LT3081 using a positive referenced logic signal?"  I get this question a lot so I will answer myself in a reply post.

I was thinking of using LT3081 regs in series to charge a series of batteries connected in series - each LT3081 keeping its equivalent battery in the series at a set voltage?

This has been done with TL431 & ancillary external transistors (see circuit…

Here is a question that I received from a customer quite a while ago, but I will post the question here and then also post the answer since the question applies to multiple LDOs and I get similar questions frequently.  Here is the customer's question:…

A customer would like to know the details about a resistor divider used in both example circuits, so I will provide the schematics in question and my response in a REPLY post.

在LT3081的datesheet中有关电流限制的描述是这样的

但在后面的一个参考电路中，3A的电流限制，电阻用的3K如果按照上面的公式计算，根本达不到3A

在评估板的电路中，按照上面的电阻最大计算也，达不到3A

是我理解错误了吗？

Hi,

I want to design a variable power supply (10 to 24V) as a part of a test equipment and want to use the LT3081 because of its nice current limiting and monitoring features. My idea is to use a buffered DAC and connect it to the SET pin. Is this possible…
