ON Semiconductor NCP1117DT25RK Voltage Regulator

The NCP1117DT25RK by ON Semiconductor is a robust fixed output voltage regulator designed to deliver a stable 2.5V output. This high-performance component is part of the NCP1117 series, which is known for its high current capabilities and low dropout voltage performance. The device is particularly suitable for a wide range of applications, including but not limited to consumer electronics, computer peripherals, and industrial hardware where a regulated 2.5V power supply is essential.

The NCP1117DT25RK features a dropout voltage of typically 1.2V at a full load, ensuring efficient operation even when the input voltage is close to the output voltage. This characteristic is particularly beneficial in battery-operated devices where the input voltage varies with battery charge levels. With a maximum output current of 1A, this voltage regulator can handle moderate to high power requirements with ease.

ON Semiconductor has designed the NCP1117DT25RK with thermal shutdown and current limit features, enhancing the safety and reliability of the device. The thermal shutdown mechanism protects the regulator from overheating, while the current limit feature safeguards it against output short circuits and overcurrent conditions. These protections ensure the longevity of both the voltage regulator and the device it powers.

The NCP1117DT25RK is available in a TO-252 (DPAK) package, which is known for its compact footprint and excellent power dissipation characteristics. This package makes it a suitable choice for space-constrained applications while providing adequate heat dissipation for reliable operation under varying conditions.

Overall, the NCP1117DT25RK is a versatile and reliable component that offers a combination of low dropout performance, high current capability, and protective features. It is an excellent choice for designers looking to ensure a stable and safe power supply in their electronic projects.
