TPS7B7701-Q1: Loop response of very low load current

Part Number: TPS7B7701-Q1

Hello Experts,

My customer would like to know the loop response of very low load current such as 10mA. I did Webench but Webench cannot simulate the loop response when Iload set less than 0.5A. Do you have any idea to simulate such condition?

Best Regards,
Fujiwara

    Hi Fujiwara-san, 

    The loop response cannot be simulated using PSPICE or webench. I would recommend using the load transient test to do the stability check as explained in this app note. 

    Please let me know if you have any questions regarding the method described in the app note.
