Working Principle

The S-1142A32H-E6T2U is a linear voltage regulator, meaning it uses a linear regulating integrated circuit (IC) to regulate the output voltage. The IC works by adjusting its output voltage based on the input voltage and the desired output voltage.In order to do this, the S-1142A32H-E6T2U features a control loop. It consists of a differential amplifier, which compares the output voltage of the regulator to a reference voltage, and adjusts the current through a power pass device. This is used to adjust the output voltage to the desired level. If the output voltage is too high, the regulator will reduce the current through the power pass device in order to reduce the output voltage.
