LP8732-Q1: Soft start function on LDOs

Part Number: LP8732-Q1

Tool/software:

Hi team,

LP8732-Q1 has the soft start function on LDOs, but users cannot configure the soft start function. Is my understanding correct?

Best regards,

    Hi Yamamoto-san, 

    The soft start feature of LP8732-Q1 is used to describe the behavior of the BUCKS, starting up from 0 V → 0.35 V before the slew rate control.
    This is not configurable. This is a built-in function.

    The LDOs do not have a soft start feature, as this is not typical for LDOs. The typical startup time for LDOs is 300 us, including delay and slew rate is ~15 mV/us, this also cannot be changed.

    Best Regards, 

    Sarah
