ZXRE125FRSTOB

A voltage reference, also known as a source of reference or a reference source, is an electronic device that produces a fixed, highly accurate DC voltage. Voltage references are used to set precisely the voltage output of a DC power supply, used in oscillators to maintain the amplitude of waveforms over frequency and temperature changes, used to stabilize the gain of amplifiers and converters, used to establish a point of reference for measurements and calibrations, and used as part of signal processing systems.

Today, voltage references are designed for working in different fields, like computers, audio-visual equipment, laboratory instrumentation and aerospace systems, etc. ZXRE125FRSTOB is one of the latest PMIC voltage references, which is built-in low drop out 0.1% reference voltage. It provides a wide range of accurate and stable reference voltages with low quiescent current.

The working principle of the ZXRE125FRSTOB voltage reference is based on a tap into a voltage divider with a well-defined resistor chain. It works by comparing two identical Zener diodes, in a process called "trim and compare", in order to achieve a precise relationship between temperatur, supply voltage and load current. The device produces an accurate reference voltage of 1.25V at 25°C. The output voltage is temperature compensated and regulated by an external reference voltage, usually provided from a digital-to-analog converter (DAC).

In conclusion, ZXRE125FRSTOB PMIC voltage reference is designed for a wide range of applications and is capable of providing a very accurate and stable reference voltage, thus ensuring reliable performance and operation. It is ideal for use in computer and electronic applications, audio-visual equipment, laboratory instrumentation, automotive systems and other applications where precise and stable output voltages are required.
