• Low quiescent current of 1.2mA

Working Principle

Linear voltage regulators, such as the REG101UA-A/2K5G4, are designed to maintain a constant output voltage. The device works by comparing the input voltage with the output voltage, and then adjusting the output current as needed to maintain the required voltage. The regulator adjusts the current flow through the pass transistor based on the difference between the input and output voltage. This adjustment is accomplished through a negative feedback loop, and the output voltage is maintained regardless of any changes in the input voltage.

The REG101UA-A/2K5G4 has three pins, which are the Ground, Input, and Output. The input voltage is applied to the Input pin, while the Ground Pin is used as a reference. The Output pin is used to connect the output signal. A bypass capacitor should be connected between the Input and Output pins to improve the stability of the regulator.
