The S-812C25AUA-C2FT2U is an advanced three-terminal adjustable linear regulator the enables a very small number of components for a wide range of power supplies. It is housed in a low-cost 2-mm package, making it ideal for space-saving applications and providing fast, close regulation. With the capability of driving up to 0.95 A of adjustable current, the device is well suited to a variety of consumer electronic devices, battery-operated equipment, notebook computer, communications equipment, and consumer electronics including video game platforms, flat panel TVs, and automotive electronics.

The S-812C25AUA-C2FT2U has a voltage range of 1.5V to 5.5V and allows for positive or negative output voltages. The output voltage of the device is adjustable through the use of an external resistor divider (optional p-type feedback transistor, refer to application section of the respective data sheet). The device includes an overvoltage protection feature that disengages the output if the output voltage exceeds the maximum rated output voltage. In addition, the device includes reverse current protection and over-temperature protection.

The working principle of the S-812C25AUA-C2FT2U is based on the principle of regulating the output voltage using a voltage reference and a voltage feedback circuit. The voltage reference is set by the external resistor divider. This voltage is compared with the output voltage by the error amplifier and the output of the error amplifier is then fed back to control the voltage reference and thus the output voltage. This feedback loop ensures that the output voltage remains close to the reference voltage.

The application field of the S-812C25AUA-C2FT2U is wide and includes general-purpose voltage regulation, battery-powered applications, DC/DC converters, LED backlight applications, automotive applications, and many others. In particular, the device is well-suited for low-cost and space-saving systems as it can provide a high output current of up to 0.95 A with a minimum number of external components. The device also includes protection features such as over-voltage protection, reverse current protection, and over-temperature protection for increased safety and reliability of the regulating circuit.

In conclusion, the S-812C25AUA-C2FT2U is a high-performance three-terminal adjustable linear regulator with an output voltage range of 1.5V to 5.5V and up to 0.95 A of adjustable output current. It can also provide overvoltage protection, reverse current protection and over-temperature protection making it ideal for a wide range of applications. The device can be housed in a low-cost 2-mm package.
