LM Datasheet(PDF) – ON Semiconductor

Feb 10, The datasheet has basically all of the answers. Sep 18, 16 dtaasheet. On page 11 the datasheet shows 4 capacitor manufacturers. They recommend directly the Nichicon PL series.

Available Distributors with stock: Those aren’t in the chart, have you run through the equations on pages 11 and 12 to get the values needed? Yes, my password is: With the help of OEMsecrets we show for all Selectors and products worldwide distributor inventory and prices.

Below you can find matching inductors from Wuerth Elektronik calculated on the maximum parameters of LM Your name or email address: It’s a parasitic aspect of lower grade caps that impedes the capacitors function. 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.


In figure 14 they show a graph of typical ESR ratings for capacitors. Nov 30, 1. The major item that changes is efficiency. Tha datasheet specifies the output capacitor capacitance range up to uF but it doesn’t specify the lowest ESR value for that capacitor. Is there any problem if my input voltage drops below LM prices and online available distributors. Transfer Multisort Elektronik 2.

From the datasheet, the capacitor should have a very low ESR at kHz. The Lm datasheet states that the output capacitor llm2595 a very low ESR can cause instability on the regulator. The datasheet shows 3. Feb 9, 7. Available Distributors without stock: Feb 10, 9.

Look at page 11 of the datasheet. Do you already have an account? For the LM replacement searchplease select a main parameter tolerance value and adjust the checkboxes for feature match.
