The product is used in mobile equipment and digital consumer applications, and when integrated, it helps provide system-level power supply and thermal management.The S-1142BC5H-E6T2U is an ultra-low quiescent current (Iq) linear voltage regulator with a maximum output current of 1.5A and a maximum dropout voltage of 100mV. It provides adjustable output voltage with a range of 3.09V to 6V at a preset voltage of 3.3V. The device is packaged in a 1-by-2 form factor, making it suitable for low-volume or space-restricted applications.

Working Principle

The working principle of a linear voltage regulator begins with a reference voltage. This reference voltage is created by a voltage divider circuit or zener diode, which is then compared to the input voltage by a differential amplifier. The differential amplifier then adjusts the output voltage according to the difference between the reference voltage and the input voltage.Subsequently, the voltage regulator transforms and limits the input voltage to a specified level set by the reference voltage. Finally, the regulated output voltage is regulated by a series connected feedback voltage divider, giving the linear voltage regulator a constant output regardless of input voltage fluctuations.
