Overview
The NCP1117DT15RKG is a part of the NCP1117 series, which are low dropout (LDO) positive linear voltage regulators produced by onsemi. These regulators are designed to provide an output current in excess of 1.0 A with a maximum dropout voltage of 1.2 V at 800 mA over temperature. The NCP1117 series includes fixed output voltages and an adjustable output version, making them versatile for various applications.
The specific model, NCP1117DT15RKG, is a fixed output voltage regulator with an output voltage of 1.5 V. It is available in the DPAK package and features internal protection mechanisms such as output current limiting, safe operating area compensation, and thermal shutdown.
