[https://electronics.stackexchange.com/questions/18384/why-does-the-lm1117-data-sheet-specifically-specify-tantalum-capacitors This info on LM1117 capacitors...].

* The minimum output capacitance required by the LM1117 is 10µF...
* The ESR of the output capacitor should range between 0.3Ω - 22Ω.
* [http://www.icbase.com/pdf/CHI/CHI00030812.pdf The ESR of the output capacitor should be less than 0.5Ω].
* Tantalums were specified because Electrolytic can have their ESR increase up to 30x on very low temps.

Maybe get some non-SMD MLCCs? Tantalums?
