#137178 - Ceramic it is, but.. Responding to: ???'s previous message |
Excellent white paper. Looks like since it's not being used for audio and I don't need the temperature range, ceramic is the obvious choice.
However, I'm still not totally clear on the ESR needs of a LP2992 linear voltage regulator. The stable range recommended is 5-400mOhm. I'm planning to use a X7R 10uF and given the limited frequency range in Table 4, I'm unsure if this will cut the mustard. Thanks Tomas |

| It\\\'s because of chip design | 01/01/70 00:00 | |
| Good Idea! But... | 01/01/70 00:00 | |
| It's not my original idea | 01/01/70 00:00 | |
| Y5V preferred | 01/01/70 00:00 | |
| Still out of stable region at low frequency | 01/01/70 00:00 | |
Only the ESR minimum of cap is what counts | 01/01/70 00:00 |
