CS5201-3GT3 is a linear voltage regulator that belongs to the category of PMIC – voltage regulators. It is designed specifically for low-noise and low-dropout applications and is available in the industry-standard SOT-223/TO-226/TO-92 packages. The voltage regulator is highly stable and efficient for a variety of applications such as automotive, telecommunications, medical equipment and general industrial.

The CS5201-3GT3 voltage regulator works by carefully controlling the current flowing through a series connection of metal-oxide-semiconductor field-effect transistors (MOSFETs) and resistors. At power-up, the voltage regulator provides an active connection between the input and output by using a feedback loop. The feedback loop keeps the output voltage tightly regulated while constantly monitoring the output voltage.

The voltage regulator features an integrated low-power standby mode of operation with adjustable hysteresis, making it ideal for automotive, portable, and standby applications. The input voltage range is 4.5V to 6.5V which makes the CS5201-3GT3 very suitable for automotive applications and other field applications that require variable input voltage. The operating temperature range of the voltage regulator is −40 to 125 °C. The device does not require external components for operation as it has integrated protection circuitry.

The CS5201-3GT3 has a junction temperature of 125°C and a peak-current capability of 6A. The low-dropout voltage of the device is 0.7V at 6A and 0.8V at 4A. The voltage regulator has an adjustable output range of 0.8 to 5.5V and it is capable of delivering up to 10A output current. This makes the device ideal for application in smartphones, tablets, and other consumer electronic devices.

The device is also designed with a built-in short-circuit protection for the load current. If the load current exceeds the safe limit, the current limits in the device will shut off the voltage regulator and protect the connected electronic components from damage. This ensures the long-term reliability of the application.

The CS5201-3GT3 also has a low-noise, high-PSRR operation that ensures minimal switching interference and noise, making it suitable for sensitive audio and video applications. The low-noise operation is due to a wide power-supply rejection ratio (PSRR) of 80dB at 1kHz and 52dB at 10kHz. This makes the device an excellent choice for applications requiring high-washing and high-dissipation performances.

In summary, the CS5201-3GT3 is a stable and efficient voltage regulator specifically designed for low-noise and low-dropout applications. The device is available in industry standard SOT-223/TO-226/TO-92 packages and features an adjustable output range of 0.8 to 5.5V. The voltage regulator is ideal for a variety of applications such as automotive, telecommunications, medical equipment and general industrial. The low-power standby mode of operation and wide PSRR makes the CS5201-3GT3 an excellent choice for diverse applications.
