Brief overview\n-- Q1002, R1003, D1002 preform an active transient protection. It will suppress voltages up to 200V. \n-- Q1001, R1001, D1001 preform a reverse polarity protection. If the input signal is the wrong polarity, the gate will not conduct which will prevent current from flowing. \n-- D1003 is a second transient suppressor, it would catch faster transients allowing a brief amount of time for Q1002 to preform it's duty. \n-- C1001 is a bulk cap, it simply stores energy locally such that the regulator can draw large currents in short periods of time. \n-- U1001 and the components to the right, are a buck style switching regulator, that will pull the 5V line up to 5V. It will now pull it down from 5V if there is an external voltage.
