Conventionally, the design of DC power supplies in different applications and systems is a challenging task for engineers. When the stability and reliability of a DC power supply is considered to be of utmost priority, the designers choose to implement the Linear type voltage regulators. Linear voltage regulators offer good precision control of the output voltage, good efficiency and excellent long-term stability suffering from low temperature coefficients. Moreover, linear regulators are very cost effective and reliable for isolated applications. With their features, these voltage regulators are ideal for low voltage applications like battery-powered systems, telecom devices, and hand-held devices. The CS8371ET7 is a Linear type voltage regulator designed by CEC（Ceramate Technology Co., Ltd.）. It was released at the beginning of 2019, making it one of the latest offerings in the PMIC - Voltage Regulators - Linear portfolio. This device is capable of delivering an output voltage of 3.3V with a maximum output current of 700mA. The CS8371ET7 enables near-zero power-supply rejection (PSRR) and is suitable for use in a wide range of applications, as it has a wide regulator voltage range of 1.5V to 3.75V.The CS8371ET7 is primarily a Linear Voltage Regulator (LVR) chip, but it also contains an important set of protections that protect the system in case of possible overvoltage, overcurrent and overtemperature conditions. The first layer of protection is a built-in overvoltage protection or OVP, which will limit the output voltage by generating a low-impedance signal. This signal is used to turn off the switch circuit, and thus the current will be limited to a safe value. The second layer of protection is an overcurrent limiter, which will cut off the load current when an overcurrent warning signal is detected. Lastly, an overtemperature protection, which consists of sensing the temperature of the device and shut down when a predetermined temperature threshold is exceeded.The CS8371ET7 has a number of features which make it an ideal choice for power system applications. It has an input quiescent current of 0.6mA, indicating its energy efficiency. Furthermore, the device is designed to be highly cost-effective, as it comes with an extended voltage range and advanced protection functions. In addition, the device has a low output ripples ratio and high PSRR, making it perfect for low-noise noise operation. These features make the CS8371ET7 a suitable choice for applications like battery-powered systems, cellular phones and IoT devices.The working principle of the CS8371ET7 can be classified as an active source regulation. It operates by maintaining a stable output voltage level, regardless of the input voltage fluctuations or of any changes in the load current. The device uses two voltage error amplifiers (VEA) – one positive, and one negative. One amplifier is used to adjust the output voltage in order to keep it constant, and the other one is used to compare the output voltage with a reference voltage, generated from a precision reference resistor. The output of the VEA will be the control signal that is used to change the output voltage by controlling the switch of the voltage regulator.To sum up, the CS8371ET7 is a Linear type voltage regulator, ideal for use in low-voltage applications. Its features of high precision control, good efficiency, and excellent long-term stability make it suitable for a wide range of power system applications. Moreover, its built-in protection features have been designed to protect the system from overvoltage, overcurrent, and overtemperature conditions. In addition, the device is extremely energy efficient with low input quiescent current, potentially decreasing the total power consumption of an application and making it more cost-effective. Lastly, the device is capable of providing high precision control of the output voltage using the active source regulation technique.
