Almost any low ESR electrolytic or tantalum capacitor will do.<br /><br />However, you can also use a ceramic capacitor provided you add a very small resistance in series with it. A 0.1 ohm resistor is usually a good compromise.<br /><br />Do not forget to check the recommendations for the output capacitor at the datasheet of the particular linear regulator you want to use.<br /><br />Nice blog and nice article!<br />Jose Angel JimenezJotahttps://www.blogger.com/profile/16661242762362332945noreply@blogger.com
