Overview
The NCV1117DT33T5G is a low dropout (LDO) positive linear voltage regulator from onsemi, part of the NCP1117 series. This regulator 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. It features a fixed output voltage of 3.3 V and does not require a minimum load to maintain regulation. The device includes internal protection features such as output current limiting, safe operating area compensation, and thermal shutdown. It can operate with input voltages up to 20 V and is available in a DPAK package, which is Pb-free and AEC-Q100 qualified for automotive and other demanding applications.
