Hi everyone, I’ve managed to burn out the voltage regulator on my Arduino Mega 2560 (power via USB works but the Vin and power jack don’t). I have searched the forum and found a couple of threads asking similar questions but because the voltage regulator product codes in those posts differ from what the component on my board says I was hoping for some clarification on the replacement component I should use.
The code on mine is W33 7CE5(0z) - 0z is in brackets as it is under the damaged region but it ties in with the code on my Uno board - and I’ve attached a photo of the damaged part, but I’ve seen links to
- The 7805 - http://www.fairchildsemi.com/ds/LM/LM7805.pdf
- The Mc33269 - http://www.onsemi.com/pub_link/Collateral/MC33269-D.PDF
- The 7805 - https://www.sparkfun.com/datasheets/Components/LM7805.pdf
- And others…
So I’m more than a bit lost about whether I should carry on trying to find an exact duplicate of the chip currently on the Arduino and where to get it or whether I should go for a different one.
