Working Principle

The SOT23-5EV-VREG uses an open-loop voltage-regulating circuit to maintain a constant output voltage in presence of supply or load variations. The device takes the input voltage, which is typically 5V, and will adjust the output voltage level to a preset value, which is usually in the range of 3V to 5V. A resistor connected to a pin on the device actuates a feedback loop which adjusts the output voltage. This principle is known as voltage regulation. The output voltage is constantly monitored so that any variation in the input voltage will be quickly compensated. The resistor also acts as a load, where a change in the load will result in an equal effect on the output voltage.
