Introduction

A PMIC-Voltage Reference is an electronic circuit designed to provide a stable output voltage over a broad range of input voltages. This reference voltage is used as a measure of voltage accuracy in various applications. A common application is power regulation of devices in the same circuit. The REF5025ID is one example of such a device. This article will explain how the REF5025ID fits into this category and how its working principle enables applications that require stabilized and/or accurate voltage sources.

Applications

The REF5025ID is a fixed-output, wide-range precision voltage reference suitable for a variety of general purpose applications, including battery-powered designs, datacom circuits and information technology systems. It provides a precise 2.5V output that can operate from input voltages from 1.8V to 5.5V, making it suitable for a range of battery-powered, industrial, instrumentation and communication circuits. Its wide supply range makes it an ideal choice for use in low-voltage and medium-voltage power supplies and applications that require a stable and accurate reference voltage.

The REF5025ID is also a low power device and can be used for portable and automated equipment, as well as in industrial systems. Its low power consumption and wide input/output voltage range make it highly suitable for applications such as battery-powered devices, motor control systems, industrial measurement andregulation systems, servo systems, embedded systems, medical equipment and automotive systems where a regulated and/or precise voltage sources is required.

Working Principle

The REF5025ID works on the principle of thermal stabilization. It uses a reference diode to keep the output voltage stable and accurate over temperature changes, as well as current and voltage fluctuations. The REF5025ID is designed to maintain a very precise input-to-output voltage ratio, and can provide this level of accuracy without relying on external feedback or trimming.

The reference diode is connected between the input and output voltage levels and is designed to absorb any changes in the input voltage. This diode is capable of dissipating the heat generated by voltage fluctuations, thus maintaining a stable temperature across the device and maintaining the input-to-output voltage ratio.

The REF5025ID also utilizes a constant current source to maintain stability. This current is designed to continuously monitor the input voltage and to adjust the output voltage accordingly. This ensures that the output voltage remains precise and stable, even under fluctuating input voltage conditions.

Conclusion

The REF5025ID is a precision voltage reference IC that provides precise and stable output voltages over a wide range of input voltages. Its thermal stabilization and constant current source principles enable it to maintain precise and stable output voltages, even under varying input voltage and temperature conditions. This makes the REF5025ID ideal for low power, battery powered, and portable electronic systems, as well as a variety of industrial, instrumentation, and communication applications that require accurate and stable voltage sources.
