Working Principle

The LP87332ARHDRQ1 employs an integrated low dropout regulator (DC/DC) to provide a regulated output voltage with very low noise and ripple. The integrated circuit contains an error amplifier, a reference voltage source, and a voltage divider to sense the output voltage.The error amplifier is responsible for regulating the output voltage by comparing the feedback voltage to the reference voltage from the voltage divider. If the output voltage drops, the error amplifier compensates by driving the MOSFET gate higher to boost the output. Similarly, if the output voltage is too high, the error amplifier lowers the MOSFET gate lower to reduce the output. Thus, the error amplifier ensures that the output voltage is maintained at a constant level.
