TEXAS INSTRUMENTS LM3940ISX-3.3/NOPB. 芯片, 稳压器, LDO, 3.3V, 1A, TO-263, 整卷
The is a low-dropout LDO Linear Regulator designed to provide 3.3V from a 5V supply. The device is ideally suited for systems which contain both 5V and 3.3V logic, with prime power provided from a 5V bus. Because the device is a true low-dropout LDO regulator, it can hold its 3.3V output in regulation with input voltages as low as 4.5V.
