Overview
The NCV1117DT50RK is a low dropout (LDO) positive linear voltage regulator produced by onsemi. This device is part of the NCP1117 series, which is designed to deliver high current with minimal dropout voltage. The NCV1117DT50RK specifically provides a fixed output voltage of 5V and can supply up to 1A of output current. It features a maximum dropout voltage of 1.2V at 800mA, ensuring efficient voltage regulation across various operating conditions.
This regulator is known for its high accuracy, with the output voltage trimmed to within ±1.0% accuracy through on-chip trimming. It also includes internal protection mechanisms such as output current limiting, safe operating area compensation, and thermal shutdown, making it a reliable choice for various applications.
