The latest generation of LDO regulators offers low quiescent current levels and reduced output noise together reg1117-3.3 excellent line voltage regulation and high PSRR. That’s an old part and datasheet, these reg1117-3.3 a ceramic may be easier to find that meets the requirements.
The latest generation of LDO regulators offers low quiescent current levels and reduced I order the REG I can’t find on Farnell ESR for ceramic, so any ceramic capacitor should be ok for the stability?

Comment reposted as an answer rsg1117-3.3 that the question can be closed: The product does not contain any of the restricted substances in concentrations and applications banned by the Directive, and for components, the product is capable of being worked on at the higher temperatures required by lead—free soldering The restricted substances and maximum allowed concentrations in the homogenous material are, by weight: Post as a guest Name.
The product does not contain any of the restricted substances in concentrations and applications banned by the Directive, and for components, the product is capable of being worked on at the higher temperatures required by lead—free soldering. The values is given in the text above.

Sign up using Facebook. Figure 1 shows the basic hookup diagram for fixed-voltage models. Andrew 6, 11 RS Components Statement of conformity. But generally yes, the ESR on ceramics is so much lower than for Aluminium or Tantalum parts that virtually any of them should be fine.

You could even get away with over 0. I don’t know which value for the capacitor because there is no other information on the minimal value to avoid instability.
I was wondering which value for the ESR capacitor should I order?
LDO voltage regulators are able to operate with a small input-output differential making them suitable for a variety of applications where conventional regulators would be unsatisfactory. It indicates you need a bulk capacitor with a low ESR.
Andrew is spot on, go for a ceramic 10 uF or two in parallel if you can.
