Working Principle

L99PM72GXPTR works by regulating the voltage output from a given source to the desired readings using control loops. In order to control the power supply components, a differential amplifier, reference voltage and output control loop are used.

The first stage of the control loop is a differential amplifier, which compares the output voltage to the reference voltage. The differences between these two signals are calculated and the result is used to control the error amp, in order to reduce the voltage difference.

The output of the control loop is then used to regulate the output control loop. This loop is mainly responsible for the regulation of the output voltage. It utilizes the output of the control loop to adjust the voltage output from the source. The output is then compared to the reference voltage to ensure the desired output is achieved.

Once the desired output is achieved, the entire system stabilizes and the voltage is controlled within the specified parameters. As such, the L99PM72GXPTR is able to regulate power efficiently and reliably, thereby providing a stable power supply for a variety of devices.
