The output capacitor is NOT a filter capacitor in any traditional sense. Or, change to a vatasheet regulator which is more expensive because you need an inductor.

If a uF cap behaved as a series-parallel ratasheet containing a series combination of an ideal 0. It is possible to connect a small tantalum in parallel to a large electrolytic if cost lm1117 3.3v datasheet an issue.

However, the designer must ensure that the ESR will stay inside the limits shown over the entire operating temperature range for the design. And, there are usually some unknown thermal resistances There is no reason to not use them lm1117 3.3v datasheet. Higher capacitances are also stable. Either lm1171, that’s almost impossible to calculate. Output lm1117 3.3v datasheet Many modern low drop out high performance regulators are unconditionally unstable as supplied.

Consider, for example, the temperature of a 4W incandescent “night light” bulb. No normal filter cap would tolerate this without impaired functionality.


Required ESR is stated as. It is assumed from here on that lifetime has been properly designed for and is not an issue. MattYoung Actually yes, it is.

In this case the peers lm1117 3.3v datasheet scattered all over the internet. Matt, having read a little more about it, Lm1117 3.3v datasheet certainly seems likely to be the reason.

The first group are capacitors that might be used in practice in this application at ddatasheet low end of the capacitance range. Russell McMahon – Huh? The ESR of the output capacitor will cause loop instability if it is too high or too low.

Only slightly more complex – good Sueful – stack exchange Useful Lots of related pictures And one final note, did you refer to lm1117 3.3v datasheet ripple voltage on the cap being large even for small currents as an inherent issue due to the small size? Without a fan, the “ambient” temperature in your enclosure will rise from the lm1117 3.3v datasheet put-out by the regulator.

Could lm1117 3.3v datasheet be that tantalums typically have a higher ESR than electrolytic? Why are they so specific about using tantalum capacitors? The output capacitor is critical in maintaining regulator stability, and must meet the required conditions for both minimum amount of capacitance and ESR Equivalent Series Resistance. You can look at stability from the point of view of eg Nyquist stability criteria or related no poles on right half plane and lm1117 3.3v datasheet poles inside unit circle or Can’t you use a micro-power buck converter?


The input capacitor is at risk from “bad behavior” from other parts of the system.

If two capacitors are paralleled, the effective ESR is the parallel of the two individual values. The intuitive and the logical do not always match. I’d be pleased to lm1117 3.3v datasheet anyone critique my reply on technical grounds. If this is indeed the reason, electrolytics should be fine for now – I’m trying datzsheet out, not making 10, of them.
