This requirement could be met by an aluminum wet electrolytic cap or a ceramic cap. Tantalum is an OK choice but is not the best choice. Lm datasheet, lm pdf, lm data sheet, lm manual, lm pdf, lm, datenblatt, electronics lm, alldatasheet, free, datasheet, datasheets, data sheet. Output capacitance required for stability: Any capacitor which meets these specifications is suitable. I’ve daatsheet this so many times – “maintain regulator stability”.

Threeterminal positive fixed voltage regulators this family of fixed voltage regulators are monolithic integrated circuits capable of driving loads in excess of 1.

Symbol Min Typ Max. The input voltage must remain typically 1. Output capacitor Many modern low drop out high performance regulators darasheet unconditionally unstable as supplied.

The input capacitor is not overly critical when the regulator is fed from an already well decoupled system bus. Jon Bright 2 3 9. If this is indeed the reason, electrolytics should be fine for now – I’m trying something out, not making 10, of them.

The active regulator can work to reduce this ripple, but it is nice to not have your filter capacitor adding to the problem you want it to fix. The lmalmlm78xxc monolithic series is available in the to plastic power package, and the lm Home Questions Tags Users Unanswered.

The intuitive and the logical do not always match. A wet aluminum capacitor will meet this spec with ease.

There is no reason to not use them there. If the net loop feedback is positive you get oscillation. Although no output capacitor is needed for stability, it does help transient response. However, the designer must ensure that the ESR will stay inside the limits shown over the entire lm34 temperature range for the design.

Only slightly more complex – good Sueful – stack exchange. I understand the need for the capacitors, but it’s not clear to me why these should specifically be tantalum. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Devices are available with improved specifications, including. The overall feedback is described by a transfer function involving the components involved.

There are various factors and cost is one. I’m still a little puzzled about why they specifically call out tantalum so much, but your answer makes clear that I can overlook this.

Lots of related pictures. Output capacitor ESR required for stability: The first group are capacitors that might be used in practice in this application at the low end of the capacitance range. It is assumed from here on that lifetime has been properly designed for and is not an issue.

It’s called “peer review”, and it’s basically what all the scientific papers go through. It’s adequate to say that the feedback from output to input does not reinforce oscillation and that a resistance that is too large or too small may lead to an overall reinforcement when considered as part of the overall system.

To provide loop stability they require an output capacitor which has both l3m40 and ESR in selected ranges.

In this case the peers are scattered all over the internet. Fixed output voltage regulator om340 if the regulator is located far from the power supply filter.

No normal filter cap would tolerate this without impaired functionality.

Because if someone like you finds something wrong you are able to correct it. The ESR of the output capacitor will cause loop instability if it is too high or too low. An eg 10 ohm resistor could be placed in series with the capacitor without impeding its functionality.

Required ESR is stated as 0.

Datashwet adequate heat sinking is provided, they can deliver over 1. The only reason for choosing tantalum might be lifetime, and this can be designed for with aluminium wet electrolytic caps. Its principal role is to provide loop stability for the regulator. Tantalum serves no technical purpose here.
