LD1117 5 Volts to 3.3 Volts regulator

Hello, I want to implement the circuit I attach.

As I see it needs 2 ceramic capacitors.

I have one 100nF ceramic capacitor but I did not find the ceramic 10μF capacitor. If I use a 10μF electrolytic instead, will the circuit work, or I will have problems?

The 10 uF capacitor typically is electrolytic. For best results, connect another 0.1 uF capacitor (paper or ceramic) in parallel with it.

So on the output I connect the electrolytic 10μF in parallel with 0.1μF electrolytic and on input I connect the ceramic 100nF?

Yes, correct. The capacitors are needed by the internal circuits of the regulator to stabilize the operation.
