voltage regulator problem
(OP)
Hi all,
I am trying to use a fixed 2.7V voltage regulator (MIC5219-2.7YM5), and the voltage output is 1.4V when I wire it according to the datasheet and supply it with anywhere from 2.5V to more than 5V. When I tried putting a load on it (20K), the voltage drops to almost zero. Any idea why this is? I ordered three of these regulators and got the same result when I tried all of them. Thank you.

What is the input voltage to the regulator when you load it up?

Did you see any wild HF oscillation on the output?

Everyone here has at some stage or other in their career, learned a similar lesson.
