LP2951 Spice Model vs. Circuit Schematic in Datasheet

Hi Markus,

I am not 100% familiar with the part, but when I look at the datasheet of the part, there is no picture on page 17, could you clarify?

Hi Herman,

i see i gave the wrong page nr. Have a look at page 18.

Hi Markus,

If you are referring to possibility of matching the model with the "Functional Block Diagram", to certain extent you can, but it's not a guarantee because the internal implementation might be different from what's shown in the datasheet as long as we match the system level performance.

If you want to trace the internal node to certain extent, you can try to trace it from the external pins. For instance, if you trace it from "Error" pin, you should be able to identify some internal nodes that eventually will lead to comparator / hysteresis that is also connected to "Feedback" pin.

Hi Herman,

thank you for your answer! Is it possible to contact you directly per Mail. I have further questions and somehow this forum doesn't allow to scetch them in a proper way?

Hi Markus,

FYI, I just send you "friend request" or "E2E Secure Messaging System". You can reply on that message.

Next time, you can click on the username of the other E2E users and then on the right hand side of the page, there will be "+Connect" button and you can "request friendship" to start the conversation.

Hi Herman,

thank you for your help. Indeed i want to build up a controll loop und therefore i want to build up my controll equations for my loop. I just want to understand where exactly the the buildingblock nodes matches in the spice file. Is it possible to provide me help in this question?

Best regards,
Markus
