Good voltage regulator tester?
(1/1)
Axtman:
Is there a good, inexpensive voltage regulator tester? Most transistor regulators I want to test are from 5 to 18 volt.
Kim Christensen:
Probably better to buy a power supply and an electronic load. Those would be useful for other tasks as well, as opposed to a dedicated regulator tester.
JoeyG:
You could look at a regulator  data sheet like the classic LM7805  and see what parameters  are critical for you and these theses.

Datasheet used to give clues in the test method but now they don'.t
Messtechniker:
Some time ago I rolled my own:

A transistor tester that has a high-voltage voltage source in its circuit for testing zener diodes can easily be converted into a voltage regulator tester. A photo of such a modification is below. ;)
