Working Principle:

LP2985IBP-2.4/NOPB linear voltage regulator consists of a voltage reference, an error amplifier, and a series pass element. The voltage reference generates a reference voltage which is compared with the feedback voltage (input voltage) in the error amplifier. If the feedback voltage is greater than the reference voltage, the error voltage causes the output voltage to decrease.

The resistance of the series pass element is determined by the magnitude of the output voltage. As the voltage output approaches regulation, the error voltage decreases and the power supply is shut off. On the other hand, if the feedback voltage is lower than the reference voltage, the output voltage will increase. The output voltage is continuously adjusted until it is equal to the referenced voltage, thus maintaining an extremely all accurate output voltage.

Conclusion:

LP2985IBP-2.4/NOPB is an advanced, high performance linear voltage regulator IC suitable for a wide range of applications. It features a low quiescent current and very efficient power management, making it an ideal choice for mobile and miniature applications in extreme temperature conditions.
