ON Semiconductor NCP1117DT12G Voltage Regulator

The ON Semiconductor NCP1117DT12G is a robust and reliable linear voltage regulator designed to deliver a fixed output voltage of 1.2V with an output current capacity of up to 1A. This high-performance component is part of ON Semiconductor's expansive NCP1117 series, known for its efficiency and stability in regulating voltage across a wide range of electronic applications.

The NCP1117DT12G features a dropout voltage of typically 1.2V at full load, which allows for efficient operation even in low headroom applications. Its design ensures a low output voltage noise, making it an ideal choice for sensitive RF applications and other noise-sensitive circuits.

With built-in thermal shutdown and current limit protection, the NCP1117DT12G ensures the safety and longevity of both the regulator and the electronic system it is a part of. These protections prevent damage from overheating and overcurrent conditions, which can be critical in preventing failure of the device under extreme operating conditions.

The device is available in a TO-252 (DPAK) package, which is known for its compact footprint and excellent power dissipation characteristics. This makes it suitable for space-constrained applications while still providing the necessary thermal performance.

Furthermore, the NCP1117DT12G is characterized for performance over a wide operating temperature range of -40°C to +125°C, making it versatile for use in various environments, from industrial settings to consumer electronics. Its low quiescent current also contributes to its effectiveness in battery-powered devices, where power conservation is crucial.

Whether you're designing power supplies for microcontrollers, analog-to-digital converters, or any other application requiring a stable and reliable power source, the NCP1117DT12G from ON Semiconductor is an excellent choice. Its combination of low dropout performance, thermal protection, and stable operation ensures that your designs will perform reliably for the long term.
