VRE102CA-3

PMIC, or Power Management Integrated Circuit, is an integrated system for controlling and regulating the voltage within an electronic circuit. This is done by various techniques such as switching, linear regulators or current regulators. Voltage reference is an important function for many PMICs, and one of the most popular and reliable devices for voltage reference is the Vishay VRE102CA-3.

The VRE102CA-3 is a 2-terminal, 5.0V voltage reference device. It comes in a TO-92 package, which makes it suitable for most electronic applications, and it also has a wide operational temperature range, from -40C to 85C. Its key features include low output resistance and a low power, 1mW operating voltage.

The main application field for the VRE102CA-3 is as a voltage reference for applications such as in electronic circuits with isolated power supplies, where it is often used to provide a reference voltage for regulation. It is also useful for power measurement and other power control systems.

The working principle of the VRE102CA-3 is simple. It uses a low drop-out voltage regulator to create a reference voltage source. This regulator uses a transconductance amplifier with active transistors to convert a current signal from the input to a voltage output. This voltage is then compared to a precision voltage reference, which provides the reference voltage for the device.

This comparison stage is able to accurately adjust the output voltage, so that the output voltage is always the same as the reference voltage. This ensures that the output voltage is always exactly the same, which is the purpose of voltage reference.

The VRE102CA-3 is a high-precision voltage reference, and it is an ideal device for many electronic applications that require accurate voltage regulation. It is a reliable and cost-effective solution, and its wide operating temperature range makes it suitable for a wide range of applications.
