Working Principle

The circuit topology for the AN80L52RMSTX is based on a linear regulator, which utilizes a P-channel MOSFET and low pass filter. The P-channel MOSFET acts as a switch, turning on and off depending on the input voltage level. When the input voltage increases, the MOSFET conducts current and the load is supplied with a constant output voltage. When the input voltage drops, the MOSFET stops conducting and the load is no longer supplied with power, effectively turning the load off.

In addition, the AN80L52RMSTX also includes a low pass filter to reduce noise and ripple on the output voltage. This filter utilizes an operational amplifier and a capacitor to smooth out the input voltage and reduce noise, ensuring a clean output voltage with minimal noise.
