Title: What is this component? Three leads and a "332" label. Voltage regulator?

I don't know what this device does. The picture tells you everything I know. I have several hundred, so knowing will save them from the trash.

Case style reminds me of a Hall Effect sensor...

Looking at the number on the die, it might be distant relation of this family...  https://uk.farnell.com/tt-electronics-optek-technology/ohs3020u/ic-hall-effect-switch-3020-sil/dp/1202503 (https://uk.farnell.com/tt-electronics-optek-technology/ohs3020u/ic-hall-effect-switch-3020-sil/dp/1202503)

Now, THAT is how you ask a "what is this component" question.
Hats off!

My guess is something from Unisonic based on the UT marking.

Thank you everyone for the input. I will see if I can get one to behave like a hall effect sensor this weekend. I'll keep you posted.

The circled 2 logo on the package is from Sprague.

It could be one of their early Hall effect sensors.
