I think your simulation results are correct. I just opened SET on the LT3082 demonstration circuit with your conditions and the output voltage increased to VIN - VDROPOUT.
I'd like to use the LT3082 in a DAC controlled mode as shown in the typical applications section of the datasheet, but I'd like to do so without the gain stage shown. This should work as the op amp internal to the LT3082 has very high input impedance…
如果試的話 可以參考這顆LT3082 Datasheet and Product Info | Analog Devices

在如果你是要定電壓 但輸出要有4-20mA 的話
The AD5270 is supplied with 5V (provided by a Zener Diode) on VDD and the VSS and GND Pins are connected to the board ground reference(DUT_S), as seen in the schematic below.
The LT3082 sets a voltage on the output depending on the resistance between…
The image below shows the basic concept of how to control an LDO output using a DAC. The LT3082 in the image is a positive LDO and the LT3090 that you want to use is a negative LDO, but it should still be possible to drive the LT3090 SET pin in a similar fashion…
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.
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.
