Overview
The NCP1117DTARKG, produced by onsemi, is a low-dropout positive voltage regulator that is part of the NCP1117 series. This series is known for its high current capability, low dropout voltage, and enhanced output voltage accuracy. The NCP1117DTARKG is specifically packaged in a DPAK (TO-252) case, making it suitable for applications requiring efficient heat dissipation and compact design.
This regulator can provide an output current in excess of 1.0 A with a maximum dropout voltage of 1.2 V at 800 mA over temperature. It is available in both fixed and adjustable output voltage configurations, with fixed output voltages ranging from 1.5 V to 12 V and an adjustable output option from 1.25 V to 18.8 V.
