I see the 330 ohm resistor as more of a current limit element for initial power on with an uncharged 100 uf cap...
...
But no one talked about the values of resistors
Why 330 ohms and 2200 ohms?
Sometimes I wonder why I even bother... The 330 ohm limits the peak current draw from the battery so the current dips on the left side wont change the battery voltage too much ....
