Hi!

I need to simulate the Load and Line regulation of the following regulators:

R-78C.0-1-0_19-5V
tps780_5-3.3V
ADR3412-3.3-2.2V
ADP1706_5-3.3

Is there a way to do this?

 

Hi,

Yes, change the load from min to max, change the input from min to max.

Usual tests for good regulators would be to very the input in three steps:
min, half, and max,

and vary the load in three steps:
min, half, and full.

You should take numbers for all three inputs and all three outputs, forming 9 separate cases.
You can then compare the results to see how good the regulator works.

 

yes.

Read the DATASHEET for each device. A good DATASHEET will show the test conditions and you'll know exactly how they were tested.

 

I'm sorry should have explained my question better. there are no models for the above said regulators. is there a way to get the spice model?

 

Hi

Try the manufactures site, search the internet, or make the model yourself.
I can make the model for you but it will take a while. Which simulator are you planning to use?

Hi,
Thanks. I'm currently using LTSpice. Could you tell me how to model these regulators, so that i could try them out as well?
