I’ve checked Yuritsh excellent thread with no luck.
Package: SOT23-5 Marking: AD2RC Coil (SW) is connected to pin 3. Input voltage (3.3V) goes to pin 4. Ground goes to pin 2. Feedback (FB) I guess is pin 5, because there’re two adjusting resistors there. Pin 1 has 4.45V No diodes or transistors in circuit. Output voltage is 1.2V, so it’s a step-down or buck regulator. |

Sorry, I searched for AD2 instead of just AD. 
Thanks! 
I had another one to look, with marking S15A3, but I won’t fall again into the same error. It’s a APS2415. But the best of all is that I think I can replace a SY8009A with a APS2415, which is the final question I was trying to answer!! |
