I wasn’t criticising you – sorry if it seemed that way. If the net loop feedback is positive you get oscillation. It’s called “peer review”, and it’s basically what all the scientific papers go through. Required ESR is stated as 0. There is no reason to not use them there. See detailed ordering and shipping information in the package dimensions section on page 16 of this data sheet.

Look at the output with an oscilloscope and you dxtasheet see an eg kHz semi sine wave of ‘s of mV to some Volts of amplitude on a nominal 5VDC output. They say in the LM datasheet. XX these two digits of the type number indicate voltage. Average Temperature Coefficient of Output Voltage.

It depends on what you datasbeet powering but it’s not usually all that critical unless ripple and transient response are especially critical for you. If needed, use a 0. Lm datasheet, lm datasheets, lm pdf, lm circuit.


The input capacitor is not overly critical when the regulator is fed from an already well decoupled system bus. Only slightly more complex – good Sueful – stack exchange. The overall feedback is described by a transfer function involving the components involved.

Still, I’d like to know for sure. Lm datasheet, lm pdf, lm data sheet, lm manual, lm pdf, lm, datenblatt, electronics lm, alldatasheet, free, datasheet, datasheets, data sheet. This can be made much smaller than a discrete circuit made from independent.

A spike more than a small fraction above a tantalum capacitor’s rated value risks it’s total destruction in a high energy circuit, such as this one is. Output 1 2 3 Heatsink surface is connected to Pin 2. If the feedback is negative overall the system is stable and the output is DC. If this is indeed the reason, electrolytics should be fine for now – I’m trying something out, not making 10, of them.

Absolute maximum ratings are those values beyond which damage to the device may occur. If adequate heat sinking is provided, they can deliver over 1.

Thank you for the extremely detailed and helpful answer.


This requirement could be met by an aluminum wet electrolytic cap or a ceramic cap. Sign up using Email and Password.

I’ve read this so many times – “maintain regular stability”. Although designed primarily as a fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents. Solid tantalum capacitors have a more stable ESR over temperature, but are more expensive than aluminum electrolytics.

Its principal role is to provide loop stability for the regulator. Heatsink surface is connected to Pin 2. The following is what you may see in typical circumstances – actual results vary widely but this is a guide. This type of capacitor is not well-suited for low temperature operation. Peter Mortensen 1, 3 14 Devices are available with improved specifications, including.

If needed, use a. The 10 uF, 10V is about half the allowed ESr – perhaps a bit close for comfort across lifetime. This family of fixed voltage regulators are monolithic integrated circuits. Why are they so specific about using tantalum capacitors? Required ESR is stated as. It is assumed from here on that lifetime has been properly designed for and is not an issue.

The output capacitor is more crucial.
