Hi
I want to make a bench supply with fixed voltage of perhaps 12VDC and 15VDC.
Doing so, I am thinking about having a high enough main supply of like 13-14V or 30V?, and then using either a zener diode or voltage regulator to create the correct Vout on the bench supply.
Are there any reasons to chose a dedicated voltage regulator like LM78XX instead of zener diodes?
Can zener diodes be found, which are capable of handling 1A?
