With the price of tantalum these days I would recommend using one of your electrolytics with a small ceramic capacitor in parallel – say nF. The input voltage must remain. Solid tantalum capacitors have a more stable ESR over temperature, but are more expensive than aluminum electrolytics.
It is possible to connect a small tantalum in parallel to a large electrolytic if cost is an issue. In this case the peers are scattered all over the internet.
Tantalums have a low ESR! 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.

Only slightly more complex – good Sueful – stack exchange Useful Lots of related pictures 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?
Tantalum serves no technical purpose here. A spike more than a small fraction above a tantalum capacitor’s rated value risks it’s total destruction in a high energy circuit, such as this one is. Although designed primarily as a fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents.

What exactly would happen?
Russell McMahon k 9 Wikipedia isn’t the free-for-all you seem to think it is. I meant to comment on Jon’s query why they would spec tantalum given the apparent lack of need for it.

Fixed output voltage regulator required if the regulator is located far from the power supply filter. No normal filter cap would tolerate this without impaired functionality. The following is what you may see in typical circumstances – actual results vary widely but this is a guide. The input capacitor is at risk from “bad behavior” from other parts of the system. Output capacitor ESR required for stability: 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.
If ultra low impedance is desired then use of a smaller parallel ceramic is indicated. Would the output oscillate with high ripple or be undefined or what exactly would happen? See detailed ordering and shipping information in the package dimensions section on page 16 of this data sheet.

Output capacitor Many modern low drop datashedt high performance regulators are unconditionally unstable as supplied. If needed, use a 0. The active regulator can work to dataasheet this ripple, but it is nice to not have your filter capacitor adding to the problem you want it to fix. MikeJ-UK 5, 11 The following is comment on what you may see in typical circumstances – actual results vary widely but this is a guide.
They say in the LM datasheet. Also, how exactly does the ESR come into play here? Although designed primarily as datasheeet fixed voltage regulator, these devices. ISC — —.
