Overview
The NCP1117DT33RKG is a low dropout (LDO) positive linear voltage regulator from onsemi, designed to provide a stable output voltage of 3.3V with an output current in excess of 1.0 A. This regulator features a maximum dropout voltage of 1.2 V at 800 mA over temperature, making it suitable for a wide range of applications. The NCP1117 series, which includes the NCP1117DT33RKG, offers fixed output voltages and an adjustable output option, with no minimum load requirement for fixed voltage output devices. The regulator also includes internal protection features such as output current limiting, safe operating area compensation, and thermal shutdown.
