The S-8424AAFFT-TB-U is a PMIC (Power Supply Controllers, Monitors) with two voltage regulators. It is designed for use in industrial equipment where efficiency and accuracy of power management are essential. The device is optimized for low quiescent current, low capacitive loading, small size, and easier circuit design. The S-8424AAFFT-TB-U features a wide input voltage range, low noise and high efficiency.

The S-8424AAFFT-TB-U application field is Ultra Low Dropout (ULDO) voltage regulators with excellent high-frequency performance. It is suitable for a variety of applications including but not limited to portable and embedded equipment, such as notebook computers, power failure interrupt controllers, and other products. It can be used as a secondary power supply (VOUT) or supply noise-suppressing power for digital signal processors (DSPs).

The S-8424AAFFT-TB-U has two voltage regulators. The first regulator is a 200mA low-dropout regulator (LDO) for powering circuits that require higher current than a regulator can provide. The second regulator is a 150mA linear regulator with an adjustable output voltage (VOUT) range from 0.8V to 5.5V. Both of these regulators feature ultra-low quiescent current (10μA) and high efficiency for portable and other applications.

The main feature of the S-8424AAFFT-TB-U is its working principle. It works by first applying the input voltage source (V IN) to the regulator’s internal power switch and then to the load. This switch is controlled by the output voltage generated through the internal error amplifier (EA). The EA provides feedback to the power switch and adjusts the output voltage accordingly. The output voltage is then regulated via the internal Low Dropout voltage regulator and linearcontrol circuit, which also provides temperature compensation.

The S-8424AAFFT-TB-U is capable of providing up to 5A of output current and is suitable for use with a wide range of loads. The device also includesprotection features that help to protect against over-voltage, over-current and thermal overload. Additionally, the device is designed with a shut-down pins that allow the user to control the output voltage and current of the regulator.

The S-8424AAFFT-TB-U is an ideal device for low noise and high efficiency systems. It offers low quiescent current, and can operate at wide input voltage range. It also provides excellent transient response and high power supply rejection ratio (PSRR). Furthermore, its fully integrated solution makes it an excellent choice for circuit designers who want to minimize their design time and effort.
