## Customer Reviews

### ⭐⭐⭐⭐⭐ Good little regulator
*by  ***  on 12 July 2025*

Nice little 3.3v regulator, works fine. Bought a pack of 10 but only used 2 so far with no issues.

### ⭐⭐⭐⭐⭐ Good quality low price 3.3v regulators
*by B***M on 10 June 2025*

Good quality 3.3v regulators with 3 0.1 spacing pins, so ideal for breadboard.Then include in your project.

### ⭐ They do not fail safe
*by S***N on 27 July 2024*

I tested the regulator before using in my equipment, and it worked fine. On about the third time of powering on my project, the regulator started to smoke. As it shorted out the 12V supply to the output, it destroyed the Raspberry Pi Pico W on my PCB - the whole board is wrecked. I am annoyed in the extreme. I do not recommend.
