FAN2564UC25X is an ultra-low dropout (ULDO), low quiescent current, 200mA linear regulator. It is fabricated using a silent monolithic process, where advanced Bipolar technology is combined with an advanced circuit design to ensure high performance, small size, and low cost. The regulator features excellent load and line regulation and high output accuracy.

The FAN2564UC25X is targeted to battery-powered systems, especially those that require ultra-low dropout performance with high power supply rejection. The device is available in space-saving/lead-free TSOP-6L/SOT-89L packages. It is designed to support a wide input voltage range from 2.5VDC to 25VDC.

The FAN2564UC25X can be used in applications such as custom power supplies, notebooks, tablet PCs, and other consumer electronics products. It can also be used in automotive, mobile and telecom applications, portable device battery chargers, point-of-use voltage regulators, etc. The device is specifically tailored for use in battery-powered applications that require an ultra-low-dropout performance with a high power supply rejection ratio.

The FAN2564UC25X is a three-terminal adjustable voltage regulator. It requires two external components-an external resistor set connected to the ADJ pin and an external capacitor connected between the output and the ground. The ADJ pin sets the output voltage of the regulator using an external resistor. The output voltage is set as follows:

Vout = 1.24V (1 + Radj/Rset)

The FAN2564UC25X has a very fast transient response, which allows it to provide a stable output voltage even with a very large load current change. It has an adjustable current limit for over current protection, which allows for efficient operation by preventing thermal runaway. The device also has an overtemperature shutdown feature, which ensures safe operation in case the device overheats.

The FAN2564UC25X also provides reverse current protection, which prevents current from flowing out of the output back into the input. An anti-phase oscillation circuit is also provided, which minimizes oscillation caused by interfacing to other components. In addition, the device also features a low perturbation voltage output pin, which helps to minimize noise generated by the regulator.

Overall, the FAN2564UC25X\'s advanced design and features make it an ideal choice for applications requiring an ultra-low dropout performance. The device\'s low quiescent current and high power supply rejection ratio make it highly suitable for battery-powered applications. The device\'s adjustable current limit, reverse current protection, and anti-phase oscillation circuit also help to ensure efficient and safe operation.
