An integrated circuit or monolithic integrated circuit also referred to as an ic, a chip, or a microchip is a set of electronic circuits on one small plate chip of semiconductor material, normally silicon.

If I’ve missed something or made a significantly incorrect technical assertion then by all means say. It’s called “peer review”, datashret it’s basically what all the scientific papers go through.
This can be made much smaller than a discrete circuit made from independent. Lots of related pictures. BUT anything can happen. Electolytics have poor high frequency performance compared to tantalums.
The second group are what would be used with Cadj bypassed and could be used anyway – ESRs are far away from limits in both directions. Wikipedia isn’t the free-for-all you seem to think it is.
And one final note, did you refer to the ripple voltage on the cap being large even for small currents as an inherent issue due to the small size? Sign up or log in Sign up using Datasjeet.

To provide loop stability they require an output capacitor which has both capacitance and ESR in selected ranges. Why does the LM data sheet specifically specify tantalum capacitors?
It is essential that the output capacitor meet these requirements, or oscillations can result. I’ve read this so many times – “maintain regular stability”.
Matt, having read a little more about it, ESR certainly seems likely to be the reason. An eg 10 ohm resistor could be placed in series with the capacitor without impeding its functionality. Thank you for the extremely detailed and helpful answer.
ISC — —. Russell McMahon k 9 XX these two digits of the type number indicate voltage. Sign up using Facebook. Depending on feedback parameters you might get low frequency oscillation, slow enough to see as variations on a “DC” meter and you might get more like MHz signals.

The only reason for choosing tantalum might be lifetime, and this can be designed for with aluminium wet electrolytic caps. MattYoung Actually yes, it is. This is an extremely wide and unusual requirement. A wet aluminum capacitor will meet this spec with ease.
A tantalum capacitor is not required to meet this specification. The ESR of the output capacitor should range between 0.
Also, how exactly does the ESR come into play here? Although designed primarily as a fixed voltage regulator, these devices.
Fixed output voltage regulator required if the regulator is located far from the power supply filter. The 10 uF, 10V is about half the allowed ESr – perhaps a bit close for comfort across lifetime. Jon Bright datasheeet 3 9.
