Voltage references, or commonly referred to as Voltage Reference Elements (VREs), are precision voltage reference sources used to create a stable output voltage independently of physical conditions and operating temperature. They are essential components on power electronic systems such as power supplies, data converters and over-current protection devices. Voltage references are used to establish a reference voltage with a known, Accurate and stable level , even when the surrounding electrical and physical conditions vary or change. This stability of the reference voltage can be used to reliably adjust, monitor and control parameters in the electrical circuit such as voltage and current levels.VRE102MA is an example of a programmable Voltage Reference and its application field is in the power electronics industry. It is designed to accurately regulate the output of power control and switching supplies, especially in DC/DC converters and battery management systems. It has a wide input voltage range between 5 and 30V, making it suitable for most power supply systems. It has excellent for temperature coefficient, staying within ±0.05% over a wide temperature range. Furthermore, it has a wide tolerance of up to ±2.6%, giving it good margin of error when regulating voltage levels. The working principle of the VRE102MA Voltage Reference is based on a band gap reference circuit. The band gap reference circuit is made up of two resistors and a transistor. The resistors are used to create a voltage difference that is independent of surrounding temperature, while the transistor amplifies the voltage difference to create a more accurate output voltage. The transistor also acts as an active component in the circuit, responsible for maintaining the voltage output at the set level.The VRE102MA Voltage Reference also contains other supporting components such as capacitors and other transistors for the frequency compensation, calibration and latency adjustment. It also has an adjustable programming pin which can be used to adjust the output voltage according to the circuit\'s needs. In summary, the VRE102MA Voltage Reference is a precision voltage source used in power electronics to regulate the output of power supplies and other power management systems. The reference voltage is stable and accurate, making it ideal for use in DC/DC converters and battery management systems. It works on a band gap reference circuit which is also responsible for maintaining stability of the output voltage. Additionally, the VRE102MA contains frequency compensation and latency adjustment components for added precision and stability.
