For the record, using smaller devices in parallel to get the same total rge1117-3.3 costs you more parts and assembly but brings the effective ESR down because reg117-3.3 capacitor’s ESR is in parallel with the other capacitor ESRs. Sign up or log in Sign up using Google. COO Country of Origin: 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.
Attribute Value Output Voltage 3. It indicates you need a bulk capacitor with a low ESR. Sign up using Facebook. The datasheet isn’t describing a bulk capacitor and a separate low ESR capacitor.
I will use this regulator to power from microUSB 5V to 3. Comment reposted as an answer so that the question can be closed: I order the REG Keep in mind that this is an old part and old datasheet, these days a ceramic capacitor that meets the requirements is fairly easy to find and is probably a better choice. 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.

I can’t find on Farnell ESR for ceramic, so any ceramic capacitor should be ok for the stability?
You could even get away with over 0. 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.
Andrew is spot on, go for a ceramic 10 uF or reg111-3.3 in parallel if you can. Henri Koch 22 3.

The latest generation of LDO regulators offers low quiescent current levels and reduced output noise together with excellent line voltage regulation and high PSRR. The product detailed below complies with the specifications published by RS Components. I don’t know which value for the capacitor because there is no other information on the minimal value to avoid instability. Price Each In a Tube of I was wondering which value for the ESR reg11117-3.3 should I order?
