which formula used to calculate resistor value for specific Vout in Evaluation board DC2279A.(R3,R4,R5,R6,R7,R8)
What could be value of R9(OPT) to set vout = 0.5

Hello,
I willing to imlement PSU with buck converter with LT3088 LDO and looking at example in datasheet p26 I see one portion of circuit which is of unclear function. Could someone explain what it does and how it works?
Hi Santiago,
The design that you are considering is not trivial, and thereare several factors that you will have to consider. The voltagereference is key, of course, but you also need to have a low-offset,low-drift amplifier for your gain loop, and…
各位大佬好:
小弟最近在使用LT3083设计一个功率较大(1A级别)的线性LED驱动器,方法是使用DAC输出参考电压Vref,连接到LT3083的Vset引脚,但是在测试时发现LT3083,当LT3083输出电流略大时(30mA),电流就十分不稳定。
测试条件简述如下:
1. 供电电源使用DC/DC 或者LDO时,二者测试效果无差别,电流波动大;
2. 负载使用水泥电阻 或 LED 时,二者测试效果无差别,电流波动大;
3. 参考电压Vref来源 : 使用DAC8563 或者NI 采集卡USB6009…
A customer asks concerning the LT3080: "We operate at: Vin = 3.3V Vout = 3V, Vcontrol = 5V, output current max. = 200mA. Is this ok?"
This is a common question so I will answer it myself in a REPLY post.
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:…
I get this question frequently so I will post the question and then answer myself:
"I made a mistake and did not notice that the LT3080 datasheet says for the DD PACKAGE that "EXPOSED PAD (PIN 9) IS OUT, MUST BE SOLDERED TO PCB". I made…
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.
