[Moved] Modelling the actual current from LDO

[Ghaznavi]

Hi all,

The current drawn from LDO varies with the output loading and is kind of sin wave around some DC current level. This has to be modelled or say iPulse acting as LDO has to be designed so that we don't have to use LDO anymore but model the effects of LDO into the iPulse and use iPulse instead.

Is it possible just by varying the parameters in the iPulse e.g. Current1, Current2, Period, Pulse Width, Rise/Fall time, Delay time, DC Current, etc. adn expect the same output as from LDO ?

any quick help would be appreciated, :smile:

thanks,

Sure you can do this - as for the "consumer", the load. But also you have to model your LDO with its parameters, as dropOut voltage, max. current and output impedance.
