#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? |

| Ceramic it is, but.. | 01/01/70 00:00 | |

| It\\\'s because of chip design | 01/01/70 00:00 | |
| Good Idea! But... | 01/01/70 00:00 | |

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