#137195 - LDO regs and ESR Responding to: ???'s previous message |

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. Too little ESR and it goes unstable. Too much ESR and it doesn't regulate. Tricky, eh? -a |

| Ceramic instead of Tantalum? ESR? | 01/01/70 00:00 | |
| a nice paper related to the topic | 01/01/70 00:00 | |
| Ceramic it is, but.. | 01/01/70 00:00 | |
| LDO regs and ESR | 01/01/70 00:00 | |
| naah, just know-how | 01/01/70 00:00 | |
| Odd | 01/01/70 00:00 | |
| 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 |
