NCP694DSAN10T1G

The NCP694DSAN10T1G is a linear voltage regulator from ON Semiconductor\'s PMI family of products. Designed to regulate output voltages from 1.8V to 10V, the NCP694DSAN10T1G is an excellent fit for a wide range of applications. Its features, such as its accurate output voltage and its low leakage current, also make it an ideal candidate for energy-sensitive, low power applications. In this article, we will discuss the application fields and working principle of the NCP694DSAN10T1G.

The NCP694DSAN10T1G is a three terminal, fixed output linear voltage regulator with an output voltage accuracy of ±2.5%. It is designed to provide an accurate and stable output voltage without any additional external components. The NCP694DSAN10T1G is available in several package options, including SOT-223, TO-220, SMD, and DPAK, making it ideal for a variety of applications. It also has a low operating current of only 200μA, making it an ideal choice for energy sensitive applications. Additionally, it has high input voltage capability of up to 18V. This makes it suitable for use in automotive, industrial, and consumer applications.

The NCP694DSAN10T1G is well-suited for use in automotive applications, such as engine control modules and sensors. Its overvoltage protection, thermal protection, and low quiescent current make it an ideal choice for automotive systems that require low power consumption and reliable operation. Additionally, its thermally efficient packages, such as SOT223, are also well-suited for high temperature environments. The NCP694DSAN10T1G can also be used in industrial systems and consumer applications, such as power supplies, audio amplifiers, and battery management systems.

The NCP694DSAN10T1G has an internal series pass transistor that provides a shunting current to regulate the output voltage to the desired level. This transistor is controlled by an internal error amplifier and feedback circuitry. The error amplifier compares the output voltage to a reference voltage and adjusts the transistor current to bring the output voltage to the desired level. The error amplifier also provides overcurrent and overvoltage protection. When the output voltage exceeds the specified level, the error amplifier shuts off the pass transistor and the output voltage is clamped to the specified level.

The NCP694DSAN10T1G also has an over-temperature protection circuit to protect it from damage due to overheating. The thermal shutdown circuit engages when the die temperature exceeds a certain preset level to shut off the pass transistor and protect against thermal damage. The thermal shutdown circuit is triggered by the same transistors used to regulate the output voltage and will reset when the die temperature has decreased.

The NCP694DSAN10T1G is an excellent choice for a wide range of voltage regulator applications. Its features, such as its accurate output voltage, low leakage current, and overvoltage and overtemperature protections, make it ideal for energy-sensitive, low power applications. Additionally, its thermally efficient packages make it suitable for a variety of applications, including automotive, industrial, and consumer applications.
