ADP5134 have two 300mA capable LDOs.
Could we use for 600mA LDO when we tie up those outputs?
If it can't use,
what kinds of problem appear when we use tied outputs?
I meant that instability might also occur due to other events, such as line and load steps, recovery from output short, etc.
About the adp223, here's a discussion on paralleling the outputs, and it's also not advisable to tie the two outputs..
Please let me know about ADP223.
Parallel outputs of ADM7172 for increased output current?
I'd suggest not to tie up the two LDO outputs because of instability issues you might see during transients, or disturbances in the system. You could perhaps look at some of the higher current ldos from ADI or possibly a low noise buck configuration.
Thank you very much for your support.
I understood it is no good to tie up two outputs.
because the output might be unstable by changing the load current.
you said "disturbances in the system" means outputs oscillation?
For example, ADP223 or ADP225 can tie up outputs.
What is the different from ADP5134?
I'm clear .
It might help to share the same current , if it adds small resisters at both outputs.
But these are increase dropout voltage and power loss.
That is no good idea.
Thank you again.
