Overview
The NCV1117DT50RKG is a part of the NCP1117 series, which are low dropout (LDO) positive linear voltage regulators. These regulators are 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 NCV1117DT50RKG specifically offers a fixed output voltage of 5.0 V and is available in a DPAK package. It features on-chip trimming that adjusts the reference/output voltage to within ±1.0% accuracy. Internal protection includes output current limiting, safe operating area compensation, and thermal shutdown. The device can operate with input voltages up to 20 V and is Pb-free, making it suitable for various applications including consumer, industrial, and automotive sectors.
