I would like to know how you calculate out the right values on the
(soft latchings power circuit only) for the
(P Channel MOSFET transistors and diode). I want to use 6 volts to soft latching power switch to diode to linear regulator (9v to 3.3v).
The (top) picture is of the full circuit the (middle) picture is of the simulated latching circuit and the ( bottom ) picture is the simulated linear regulator .


Here is how the soft latching Power circuit works, somebody on YouTube posted this.
