#137065 - Ceramic instead of Tantalum? ESR? |
I'm using a Linear Technology LTC2493 (A-D Converter). It recommends the use of a 10uF Tantalum capacitor along with a 0.1uF ceramic. Are there any potential negative side effects to using a 10uF ceramic instead of the tant?
Also, I have a regulator that requires a 10uF output cap with ESR between 4 and 500 milli-ohm to remain stable. Why do high capacitance ceramics not specify ESR? Thanks, Tomas |

| 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 |
