Hello , My name is Mario Martinez , i want to know about sumulation circuits of squematics what represented for analisys of energy quality and energy efficient , i am ecuatorian

The LT1083 comes in my standard library. If I substitute it for the LM317, I get no error messages. The PSRR is till poorer for OUT2. Do you still think configuring V1 as I did is incorrect? Sent:

Your LM317A_TRANS symbol has the path on your computer to the model hard-coded in its Attributes. OK, that can be fixed, but you should be aware of this pesky feature that causes trouble every time

John, Apologies. AC source enabled and .lib and .asy files supplied. ProgCurrSource_Corr uploaded. Comments below still apply. Thank you, Tony. Here’s the problem I encountered with the unmodified

If you want to keep track of voltage nets or nodes, you can give them a label name such as a or b, or in or out.? And use those names if you want.

You didn't upload the LM317 model. Your 12 V DC source doesn't have a sine wave superimposed. You do that by adding a sine generator in series. You can probably disregard the warnings abut curly

Please ignore, I see a problem with what I did. Sent: Sunday, April 6, 2025 9:58 AM To: [email protected] Subject: Re: [LTspice] Simulation runs very slowly: test.asc Thank you, Tony. Here’s the

Thank you, Tony. Here’s the problem I encountered with the unmodified LM317A_TRANS while hoping to use the DC current source I1 to create a programmable current source. See ProgCurrSource.asc. The

Correction: the TI LM317 datasheet Figure 8 shows about 65dB at 25?C, not 57dB, which is over all temperatures. But Figure 8 is not reliable, because it shows the additional 10uF capacitor on ADJ

Other planets are available. -- Regards, Tony

The notes in the LM317A model are nonsense. PSRR is modelled, although it doesn't quite stack up with the datasheet, which states 68dB (typ) - the model delivers -55dB. For comparison, for the LM317,

why i have a feeling that i just crashed on idiots planet

Ah, of course.? "Datasheet" makes sense. Andy

I took?"d/s" to Datasheet. But I could be wrong. -- Regards, Tony

I’d be interested in whatever you find, and hope that the transistor-based model you mentioned and I saw works more like an actual LM317. Sent: Saturday, April 5, 2025 5:28 PM To: [email protected]

I didn't check the LM317A. I hadn't appreciated this was a new device. Traditionally, the "A" suffix denoted a tightened tolerance of the basic device. More recently, TI started using it for

Thanks Tony. Yes, there’s the LT3080 and its ilk as well as many others. Appreciate your forthcoming effort in checking what you have and uploading it. Sent: Friday, April 4, 2025 6:46 PM To:
