Working principle

The LT1074HVCT#06PBF is a switching voltage regulator that works on the principle of pulse width modulation (PWM). It uses a control loop for regulating its output voltage. It has a switching transistor that is continuously turned on and off based on the error signal from the comparator that compares the output voltage with the given reference voltage. When the output voltage is lower than the reference voltage, the transistor is turned ON, allowing current to flow from the input to the output, thus increasing the output voltage. When the output voltage is higher than the reference voltage, the transistor is turned OFF, thus preventing current from flowing, resulting in a decrease in the output voltage. This process is repeated in rapid cycles until the input voltage and output voltage are equal, thus stabilizing the output voltage.
