The device is capable of operating down to a supply voltage of 1.8V and up to a maximum voltage of 5.5V. It is well-suited for battery-powered applications and other power-sensitive systems.

The working principle of VRE3025AS is based on a low-noise linear voltage regulation circuit. This internal circuit is used to generate a stable and accurate reference voltage when the input voltage applied across the device is higher than that to be generated. This higher input voltage is regulated to the prescribed output level by controlling the current through the output external transistor. In the VRE3025AS, the voltage drop across the output is regulated by controlling the current inside the device. This current control is achieved through the use of a low-noise, high-performance, on-chip linear regulator.

The voltage regulator is designed to minimize input voltage ripple and reduce output noise to a minimum. This helps to provide a more stable output voltage and improve accuracy levels. The on-chip voltage regulator also helps to reduce power consumption, resulting in improved battery life. This device is also able to provide efficient current-limiting protection when current sensing is used.

VRE3025AS is a low power and highly accurate voltage reference device that is ideal for a wide range of applications. The device offers excellent accuracy and stability over a wide temperature range, making it suitable for applications that require a high level of precision. Furthermore, its low power consumption makes it ideal for portable and automotive systems.
