My room thermometer is consuming a full stack 3 AAA batteries in just 24 hours. I opened it and found that maybe the component circled in green is burnt (CAZB)....
The smd codes kind of suck. They’re used on devices where there isn’t room for the full PN. But they’re not standardized well. Are often unique per footprint, but even then, not a guarantee.
I looked up “CAZ” here: smd.yooneed.one/code4341.html and found a part that matches the footprint. Then googled around and found the LN61CC3002MR-G on lcsc.
It can be very hard to find a part on Google, or say Digikey, if it’s made by a Chinese company. LCSC can be helpful since they’re based in China.
Can you identify what kind of voltage regulator (?) is this? (discuss.tchncs.de)
