I got a STM32L151C8T6 board, powered by a 3.3V button battery. But the battery died. I used STLINK to power it, and it should be 3.3V, but when I measured it with a multimeter, it was 4.77V, and somet...
The output voltage rises, the cathode voltage of TL431 drops, the P tube is turned on, and the output voltage drops.
But doesn't the transistor go directly to the ground when it is turned on? Is there...
