Power management integrated circuits (PMICs) are essential for any complex electrical system and are used for regulating and controlling power assets in a variety of applications. Voltage reference integrated circuits make up one type of PMIC, used for providing a known reference voltage in a circuit. REF5020AIDGKT is one such example of a voltage reference PMIC, and its application field and working principle will be discussed in this article.

The REF5020AIDGKT is a low-dropout (LDO) voltage reference providing precision output voltage and ensuring high accuracy in voltage regulation. It can be used to reduce supply-output errors and regulate the voltage of a signal in a wide range of applications. It is perfect for applications that require high accuracy and power efficiency, such as precision instrumentation, harsh environment instrumentation, sensor detection and signal conditioning, precision timing and low-power embedded systems.

REF5020AIDGKT is a very stable and accurate voltage reference produced on an advanced silicon-on-insulator (SOI) technology. It has a wide operating temperature range, from -40°C to 85°C, making it suitable for a variety of industrial, medical, and automotive applications. This reference voltage is extremely low noise, with a maximum output noise of 50 nV/VHz at 1 kHz and a maximum voltage drift of 600 ppm/°C over the operating temperature range. It also has a wide operating voltage range of 1.65V to 5.5V, making it suitable for a variety of power sources.

The working principle of REF5020AIDGKT is based on a band gap reference design. An amplifier is used to compare the output voltage with a stable reference voltage generated by a band gap circuit, and the amplifier is adjusted to regulate the output voltage in order to maintain a constant voltage differential between the two. The output voltage is set by an external resistor divider, and the amplifier is designed to provide a very low output impedance in order to maintain a stable output over a wide range of temperatures and resistances. This allows the REF5020AIDGKT to provide a precision reference voltage of 0.8V, 1.5V, 2.048V, 2.5V, and 3.3V with excellent accuracy.

The REF5020AIDGKT is a very versatile voltage reference PMIC with excellent performance and accuracy. It is suitable for use in a wide range of applications where voltage accuracy, low noise, and wide temperature range are required. Its band gap reference design provides stable and accurate output voltage and ensures excellent accuracy over a wide range of temperatures and resistances. Its low-dropout (LDO) design makes it power efficient and allows it to operate over a wide operating voltage range. The REF5020AIDGKT is a perfect choice for applications that require precision voltage reference.
