#138619 - Still out of stable region at low frequency
Responding to: ???'s previous message
Even the cap you suggest exceeds the 500 milli-ohm at low frequency. It shows an ESR of 10 ohms at 100Hz.

I think the only way to guarantee stability is to use a higher quality cap with some small value of resistance (.2 ohms or so).

What are your thoughts?

         Only the ESR minimum of cap is what counts            01/01/70 00:00
