At the core of the LP2981IBP-2.5 is a bandgap voltage regulator (BVR). This BVR is configured in a resistive feedback manner to provide a wide output voltage range. This regulator consists of two transistors; one is a reference transistor and the other one is an error amplifier. The reference transistor provides the voltage sensing mechanism of the circuit and the output of the error amplifier is connected to the reference transistor\'s base, allowing this circuit to regulate the output voltage. In order to regulate the output voltage, the BVR needs to sense the output voltage, compare it with the reference voltage and determine the necessary current through the pass transistor to regulate the output voltage. This current is then amplified and applied to the base of the pass transistor to regulate the output voltage.Conclusion
