Default can someone help identify this transistor

the writing reads like this exactly
l78l()5
a
GE 92()

theres some rep in it for the first to help.
if its not ethical to ask for help in exchange for rep let me know and it wont happen again.

Default Re: can someone help identify this transistor

the writing is so small it wouldnt show up.
this is exactly how it is written on the chip. its a 3 prong transistor in a semicircular shape.

Default Re: can someone help identify this transistor

Could be a TO92 5v regulator ( 78L05) .

What kind of circuit is it out of? is it a PSU by any chance?

If you measue the voltage at pin 1 it should be between 5-15v

I'm thinking ped is right.. it's most likely a 78L05 voltage regulator based on the numbers.

Sorry for the late reply, didnt see you'd asked a question..

i wouldnt say its "typical" , but it is possible.
