I spent about an hour reading posts here and cant seem to find what I need...
I have 28VDC power and need two 12VDC @ < 1A outputs... I have found some simple looking schematics for using the 78xx series regulators, for example; https://www.mybitbox.com/wp-content/uploads/2009/02/circuit.jpg, however, I have not been able to find any information on how to determine what capacitors I should use...
Also, I would like to have some level of "protection" built into the device to deal with incoming and out voltage spikes (or whatever) that may damage the convertor, or the devices I am powering with it...
Any help I could get would be greatly appreciated!
