NCP717BMX285TCG

The NCP717BMX285TCG is a linear voltage regulator, also known as a low-dropout voltage regulator (LDO). It is a member of ON Semiconductor\'s "Green" family of PMICs (Power Management Integrated Circuits) which saves energy and helps products meet stringent standards for efficiency and reduce power consumption and save energy for end-users. This regulator can provide a low-noise fixed-output voltage and features low-dropout voltage and excellent line/load regulation. It also offers a fast turn-on time, excellent thermal stability, fast transient response and excellent maximum load regulation.

The NCP717BMX285TCG is designed for use in a variety of applications, including instrumentation, industrial, automotive and consumer electronics. It can be used for voltage regulation by providing a constant output voltage, which is necessary in many electronic circuits. It can also be used to provide clean power supply, which is required by many digital and analog circuits.

The NCP717BMX285TCG operates on a power input of 1.8V to 32V DC, with an output voltage adjustable between 1.2V to 29V with a 2.5% accuracy. It also has a temperature range of -40°C to 125°C and a low quiescent current of only 250 μA. The NCP717BMX285TCG includes both over-temperature protection with auto-recovery and short-circuit protection features.

The electrical characteristics and application of this regulator can be further understood by studying its working principle. The NCP717BMX285TCG works on the principle of feedback control. It can maintain an output voltage that is proportional to the reference voltage. The output voltage is regulated by the amount of differential voltage applied across the feedback pin and the reference pin. As the output voltage increases, the voltage applied to the feedback pin also increases, which results in a proportional reduction in the current driving the output stage.

The NCP717BMX285TCG also offers a feature that allows the user to program the output voltage by inserting an external resistor. It also includes a power-good signal, which will indicate the condition of the output voltage. Additionally, the voltage regulator is protected against over-temperature and over-current conditions.

The NCP717BMX285TCG is an excellent choice for a wide range of applications that require a high-performance, low-noise, energy-efficient linear voltage regulator. The device is readily available in a small, Surface Mount SOIC-8 package, making it suitable for integration into densely crowded circuit boards and even compact hand-held electronics.
