LM2941: Figure 13

John Garrett

Part Number: LM2941

Figure 13 defines ESR for the output capacitor. Please clarify the max and min ESR at 200mA as it is not provided in the figure.

Thanks, John Garrett TI-AFA

Hi John,

As the figure is not very clear I would keep the ESR within 0.1 to 1 ohm. It is hard to read the log scale without all of the lines, but you should be safe if you stay between 0.1 to 1 ohms.

Hi John,

After reading further in the datasheet it shows the acceptable range of 0.01 to 5ohms, and that seems to match what the curve is showing.

Regards,
Mark
