Voltage reference, also known as a reference voltage or a reference, is a circuit element or device that establishes a known potential reference with respect to the voltage in an electrical system. PMIC voltage references are fixed voltage sources used as reference points in circuits to accurately control the voltages in low-voltage applications. The ZXRE125FRSTZ is such a PMIC device capable of providing a stable reference voltage level while consuming exceptionally low power. In this article, we will look into the application field and working principle of the ZXRE125FRSTZ.

Application Field of ZXRE125FRSTZ

The ZXRE125FRSTZ is a linear voltage regulator with an ultra-low quiescent current of only 5µA and excellent temperature stability of ±0.3% or better over the entire operating temperature range. This makes it especially suitable for low-power applications such as industrial and medical applications, white goods, solar-powered products, and battery-powered products. The ZXRE125FRSTZ can be used in power supplies, temperature controllers, data converters, and analog-to-digital converters.

In addition, the ZXRE125FRSTZ is well suited for use in many other electronic applications, such as automotive systems, computers, tablets, gaming systems, and communications equipment. Furthermore, the ZXRE125FRSTZ can be used in applications such as laboratory equipment, audio systems, and monitoring/measuring systems.

Working Principle of ZXRE125FRSTZ

The ZXRE125FRSTZ is a linear voltage regulator that takes input voltage and converts it to a stable, predetermined output voltage. It includes internal compensation components to maintain a stable output and prevent output noise, as well as output current limiting and thermal overload protection. The ZXRE125FRSTZ uses a reference voltage to compare incoming voltage against a fixed, predetermined level. Once the incoming voltage is converted to the predetermined level, the device outputs the modified voltage. The output voltage is also highly stable and accurate to within a few millivolts, making it suitable for many low-power applications.

The device also benefits from an on-chip temperature-compensated voltage reference (TCVR) to provide an ultra-stable output voltage, compared to conventional voltage regulators. Additionally, the ZXRE125FRSTZ can provide a very low dropout voltage, ensuring that it can operate at 1.3V and lower inputs, making it suitable for a range of modern devices with advanced power requirements.

Conclusion

The ZXRE125FRSTZ is an ultra-low power PMIC Voltage reference device, suitable for use in a variety of low power applications and systems. Its ultra-low quiescent current and excellent temperature stability make it an ideal choice for powering energy-sensitive electronics and systems, while its internal components and built-in temperature compensation allow for a highly accurate and stable reference voltage.
