VRE101MA voltage references are integrated circuits (ICs) that generate or control a fixed or adjustable reference voltage. They may control or sense either positive or negative voltages. Such devices are used to maintain a fixed level at the output of power supplies, instrumentation, and other applications needing stable reference sources. A VRE101MA voltage reference performs the regulation of the reference voltage using a standard op-amp configuration with negative feedback.

The VRE101MA voltage reference uses a series of three resistors with one reference voltage being produced by two resistors. A simple two-wire connection provides the reference voltage to the application. The built-in thermal shut-down circuitry protects the reference voltage when an over-temperature condition occurs.

The VRE101MA voltage reference has an adjustable output that can be adjusted via the onboard trimpot. It can be used to adjust the reference voltage to meet precisely the required output voltage level. The trimpot can also be used to set the output current limits in applications requiring a higher current output.

VRE101MA voltage reference is mainly used in point-of-load (PoL) regulators and linear voltage regulators. PoL regulators are typically used in communications systems, where the incoming power is regulated directly at the load. The linear voltage regulator is used for interfacing between different voltage levels and for supplying power to many types of circuits.

The working principle of the VRE101MA voltage reference is based on the concept of negative feedback. It works by comparing the output voltage of the reference to the reference voltage. The difference between the two is amplified and compared to the reference voltage. If the output voltage is higher than the reference voltage, the output voltage is reduced; whereas if the output voltage is lower than the reference voltage, the output voltage is increased. This process continues until the output voltage matches the reference voltage.

The VRE101MA voltage reference provides an excellent solution for applications requiring stable, low voltage references. Its adjustable output makes it suitable for numerous other applications. Moreover, the protection circuitry built-into the device lengthens the life of the device and provides additional safety.
