Voltage references are essential components for stable and accurate regulation of circuits. PMIC – Voltage Reference is one of the most commonly used methods to achieve precision and reliable voltage reference. The ZXRE125DRSTOB is one of the popular Voltage Reference products from ZXRE. In this article, we will discuss about the application field and working principle of the ZXRE125DRSTOB.

The ZXRE125DRSTOB is a high-precision Voltage Reference, which can be used in a wide range of consumer, industrial and automotive applications. It is suitable for applications that require extremely precise voltage references. It features an accuracies better than 0.2 % and temperature coefficient of 5 ppm/C. It is designed to provide a precise, low-voltage reference voltage of 0.125 volts.

The ZXRE125DRSTOB also offers a wide range of advantages like wide operating temperature range, adjustable output voltage, low dropout voltage, long load regulation line and high power supply rejection. It has built-in overvoltage protection, thermal protection and short-circuit protection, making it suitable for applications where power supply reliability is required.

The working principle of the ZXRE125DRSTOB is quite simple. It is composed of three basic elements: the voltage reference, a gate driver and an output stage. The first element is the voltage reference which sets the desired output voltage. It is usually composed of a differential amplifier connected to a precision reference voltage. The reference voltage is usually provided by a Zener diode but can also be provided by a transistor reference circuit. The second element is the gate driver which converts the voltage change at the reference voltage into a current change which is then amplified by the output stage.

The output stage is composed of a power MOSFET which is used to amplify the current and drive the load. This allows for a wide range of output power levels, making the ZXRE125DRSTOB very flexible in terms of operation. It has low switching noise and high power efficiency for lower power applications.

In conclusion, the ZXRE125DRSTOB is an ideal Voltage Reference for a wide range of consumer, industrial and automotive applications. It offers precise voltage reference, wide operating temperature range, adjustable output voltage, low dropout voltage, long load regulation line and high power supply rejection. It also features built-in protections to ensure power supply reliability and long-term stability. The simple working principle of the ZXRE125DRSTOB makes it suitable for a wide range of applications.
