The LD1117 data sheet makes no mention of what type of 10uF capacitor to use at the output. is it stable with ceramic there or does it, like the LM1117, need something with more ESR?

Hi Jasen, the ST datasheet says: "Only a very common 10 µF minimum capacitor is needed for stability." "High efficiency is assured by NPN pass transistor" "The adjustable LD1117 is pin to pin compatible with the other standard." (Coy reference to the LM317? LM1117?)
These suggest to me a common Al-electro type. Nothing exotic. You are skeptical of this? Or, you really want to use a ceramic type? = RS
