Item Description
Startup Delay This box sets the delay between powering up of each regula-
tor at initial power up.
POR Delay This box sets the delay for the POR flag pin. The POR delay
time starts as soon as AVIN voltage rises above the system
UVLO upper threshold.
VSLT Pin Logic Level For the MIC7401, the threshold is fixed between 2.25V and
3.25V and can’t be modified.
POR Threshold Up This box sets the POR threshold Up value from 2.25V to
3.25V.
POR Threshold Down This box sets the POR threshold Down value from 2.25V to
3.25V.
Fast Soft Clock This check box sets the speed of the clock used for soft start.
If checked, the Soft Start time is decreased by half (no matter
the value) for all regulators.
