Overview
The NCV1117DT18T5G is a low-dropout positive voltage regulator from onsemi, part of the NCP1117 series. This device is capable of providing an output current in excess of 1.0 A with a maximum dropout voltage of 1.2 V at 800 mA over temperature. The NCV1117 series is AEC-Q100 qualified and PPAP capable, making it suitable for automotive and other applications requiring unique site and control change requirements.
The NCV1117DT18T5G is available in a DPAK package and features on-chip trimming that adjusts the reference/output voltage to within ±1.0% accuracy. It includes internal protection features such as output current limiting, safe operating area compensation, and thermal shutdown.
