The ZRC400A03 is an adjustable three-terminal voltage regulator. This product offers excellent precision performance with regard to both accuracy and temperature stability over wide range applications. It is based on a Silicon Carbide (SiC) reference cell which, unlike typical band-gap references, exhibits near zero temperature coefficient and excellent tolerance to line transformer noise, making it an excellent choice as a voltage reference in precision applications.

The ZRC400A03 is feartured with a high accuracy which is 1% over line and temperature. It is a low power supply without requiring any external compensation components but with very fast response time of less than 3μsec. Its output can be adjusted externally from 5V to 20V by using the appropriate resistors. It also has open-circuit and short-circuit protection as a self-protection.

The application field of the ZRC400A03 is not limited to any specific field. It can be used in many different applications such as automotive, industrial and consumer electronics, audio and video products, data communications, and power supplies and converters. In automotive systems, the ZRC400A03 can be used as a voltage regulator in dashboards, alternator-protected voltage sensors, and motor-control systems.

The principle of operation of the ZRC400A03 is based on a bandgap reference. It uses a SiC references cell to generate a constant 1.64V reference voltage. This voltage is then buffered by an amplifier circuit and output to the output terminals after being adjusted by external resistors. The voltage reference can also be adjusted by adding external resistors. This allows the user to fine-tune the reference to the desired output voltage.

The ZRC400A03 also features overload and over-temperature protections. The over-temperature protection will prevent the chip from overheating and the overload protection will prevent it from going out of limits due to over voltage or excessive current. The chip also features a thermal shutdown feature which will reduce the current output when the temperature exceeds a certain limit. The ZRC400A03 also features a soft start feature which will gradually increase the current until the desired voltage is reached.

In summary, the ZRC400A03 is an adjustable three-terminal voltage regulator. It is based on a Silicon Carbide (SiC) reference cell which offers excellent precision performance. It is suitable for many different applications such as automotive, industrial and consumer electronics, audio and video products, data communications, and power supplies and converters. The ZRC400A03 works on the principle of bandgap reference and is also featured with overload, over-temperature and thermal shutdown protection. As it is an adjustable voltage regulator, the output voltage can also be adjusted externally.
