I was wondering which value for the ESR capacitor should I order? It indicates you need a bulk capacitor with a low ESR. Andrew is spot on, go rreg1117-3.3 a ceramic 10 uF or two in parallel if you can.

Figure 1 shows the basic hookup diagram for fixed-voltage models. 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: By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

The value reg111-73.3 given in the text above. I can’t find on Farnell ESR for ceramic, so any ceramic capacitor should be ok for the stability?

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. 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.

Attribute Value Output Voltage 3. COO Country of Origin: For the record, using smaller devices in parallel to get the same total capacitance costs you more parts and assembly but brings the effective ESR down because each capacitor’s ESR is in parallel with the other capacitor ESRs.

The latest generation of LDO regulators offers low quiescent current levels and reduced output noise together with excellent line voltage regulation and high PSRR. Sign up or log in Sign up using Google. The latest generation of LDO regulators offers low quiescent current levels and reduced Andrew 6, 11 I don’t know which value for the capacitor because there is no other information on the minimal value to avoid instability.

The datasheet isn’t describing a bulk capacitor and a separate low ESR capacitor. The product detailed below complies with the specifications published by RS Components.

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. It’s a bulk capacitor with a low ESR. That’s an old part and datasheet, these days a ceramic may be easier to find that meets the requirements.
