Working Principle

The SG2524BN voltage regulator consists of three main parts, which are responsible for the regulation of the output voltage: a power MOSFET, a voltage reference, and an internal comparator circuit. The power MOSFET acts as the output switch, which is controlled by the voltage reference and comparator circuit.

When the voltage reference voltage is higher than the output voltage, the comparator circuit will turn on the power MOSFET, allowing current to flow through the output. This will cause the output voltage to increase. When the voltage reference voltage is lower than the output voltage, the comparator circuit will turn off the power MOSFET, preventing current from flowing through the output. This will cause the output voltage to decrease.

The SG2524BN voltage regulator also has built-in brownout protection that prevents the output voltage from going below the specified minimum operating voltage. It also has an integrated start-up circuit that ensures the output voltage is within the specified operating range when the regulator is first turned on.
