The FAN2564UC15X is a linear Voltage Regulator (VR) in Power Manager IC (PMIC) that provides efficient voltage regulation in an integrated package. It is a low-dropout (LDO) voltage regulator, meaning that it can reliably regulate an output voltage as low as 0.5V as compared to 1.5V traditional regulators. This makes it an ideal choice for applications such as computing, networking, consumer and industrial electronics, where efficiency and compact form factor are key.

The FAN2564UC15X is designed to enable the lowest RDS (ON) at light load current operation. This enables excellent line and load regulation. Its fast response enables quick response and regulation to any sudden input voltage. The FAN2564UC15X has current limit and thermal shutdown features for additional protection.

The FAN2564UC15X can provide an output voltage range of 1.2V to 15V and is capable of providing up to 100mA of continuous output current. The device has a load-transient response time of less than 1μs. It also has an enable feature that can be used to put the device in standby mode and reduce power consumption.

The typical application fields for FAN2564UC15X include portable electronics, such as laptops, tablets and netbooks, powering circuits for industrial, automotive, and instrumentation systems, as well as for voltage regulation of various integrated circuits. The FAN2564UC15X is also capable of supplying the power for power over Ethernet and USB applications.

The working principle of FAN2564UC15X is to convert the input voltage from DC source to a constant regulated voltage output. The device has an internal series of transistors and resistors that establish a stable reference voltage. When the load connected to the output draws current, the voltage across the load will drop. This in turn causes a voltage drop across the series pass transistor and depending on the load current. The output voltage will remain constant even if the input voltage or load current varies.

The FAN2564UC15X also contains additional circuitries to protect the device from overload, short circuit and thermal events. It has a built-in current limit circuit that limits the current flow through the series pass transistor and thus protecting the device in the event of overload. It also features an internal thermal shutdown circuit in which the device will be disabled when the temperature exceeds its limit.

The FAN2564UC15X is a versatile LDO voltage regulator with excellent performance. It integrates a series pass transistor and reference voltage circuitry into an integrated package that provides very high efficiency and output accuracy over wide temperature and line variations. As an added feature, it also provides an enable input for power-down applications and excellent load and line regulation for very low output voltage applications. It is the ideal choice for a variety of portable and embedded applications requiring efficient power management.
