Tha datasheet specifies the output capacitor capacitance range up to uF but it doesn’t specify the lowest ESR value for that capacitor.
Below you can find matching inductors from Wuerth Elektronik calculated on the maximum parameters of LM Nov 30, 3. Available Distributors with stock: Link to the most up-to-date LM datasheet and the product page datashwet EVM, tools and support information. Allied Electronics, Inc 1. In figure 14 they show a graph of typical ESR ratings for capacitors. On many other pages they talk about the capacitors. Sep 18, 16 0.

Will the regulator work bad if I don’t respect the minimum voltage per Inductance region? No, create an account now.
What would happen if for example I have the inductor L30 68uH and my input voltage drops to 9. For the LM replacement searchplease select a main parameter tolerance value and adjust the checkboxes for feature match. Fresh Search Replacement Search with.
Could you help me with this topic please? Farnell element14 DE Feb 19, 6, LM Buck Converter overview. They recommend directly the Nichicon PL series. Get Out of My Space! Quote of the day. The product counter within the button shows the number of available equivalents and a click on the replacement button shows all possible replacements within a parametric overview.
