Reverse voltage protection

A project log for SuperCAP BKUP

A Supercap power backup solution for small devices. Small being relative, depending on the size of the cap ;)

Note to self: 

1) Linear regulators must be protected against reverse voltage through a Schottky diode in the antiparallel configuration (output to input) or a diode before the regulator (bad).

2) Do switching regulators need protection too?
