PMIC (Power Management Integrated Circuit) is an important part of the modern power supply system and plays an important role in providing and controlling the power supply. Voltage regulators are one of the important components of PMIC, and linear voltage regulators are the most common and popular voltage regulators. The S-1142C25H-E6T2U is a low dropout linear voltage regulator and is capable of providing a stable and efficient output voltage for a wide range of applications. In this article, we will explore the application field and working principle of the S-1142C25H-E6T2U.

Application Field of S-1142C25H-E6T2U

The S-1142C25H-E6T2U is a low dropout linear voltage regulator with an operating voltage range of 4.5V to 40V and an adjustable output voltage of 1.25V to 24V. This regulator offers a high output accuracy of 1.5% to 2.0%, and is capable of providing a fast transient response. This regulator can reach a maximum output current of 2A with a heatsinking the bottom. The S-1142C25H-E6T2U is widely used in the power supply system of new energy vehicles, high-power automation equipment, laser equipment, medical equipment, and industrial computers. These applications require a stable output voltage with low noise and high efficiency.

Working Principle of S-1142C25H-E6T2U

The S-1142C25H-E6T2U voltage regulator is a low dropout (LDO) linear voltage regulator. The working principle of an LDO voltage regulator is based on a voltage divider circuit. The input voltage is divided by a pair of resistors to produce a reference voltage, which is then compared to a feedback signal from the output. When there is a difference between the two signals, the error signal is used to adjust the output voltage by controlling a pass element, typically a MOSFET. The voltage reference is kept constant by using an error amplifier which provides the precise error signal. The output voltage is then set equal to the reference voltage.

The low dropout performance of the S-1142C25H-E6T2U is achieved through its two stages differential amplifier, which reduces the voltage drop by reducing the current through the control element. The two stages differntial amplifier has a higher efficiency than the single stage amplifier and also reduces the sensitivity to power supply noise. The low noise and high efficiency of this regulator is achieved with the help of its low dropout design, which ensures a stable output voltage with minimum power loss.

The S-1142C25H-E6T2U is a very popular low dropout linear voltage regulator as it offers a wide range of operating voltage and is capable of providing a stable output voltage with low noise and high efficiency. This voltage regulator is widely used in new energy vehicles, high-power automation equipment, laser equipment, medical equipment, and industrial computers.
