Hi all,
I have a question about over-voltage protection for the output of an LM338K adjustable voltage regulator.
Is there a way to create an over-voltage protection so that the protection will kick in at Vout + Vthreshold, where Vout will vary?
What I mean is that no matter what output I select for Vout the protection circuit will kick in at Vout + the treshold voltage and not at a fixed predefined voltage.
Is this a common protection method for lab adjustable power supplies? Or lab power supplies usually don't have a over-voltage protection?
Thank you,
Buzai
