The FAN1084MCX is a linear voltage regulator designed and manufactured by Fairchild Semiconductor. The FAN1084MCX is designed to provide the input of the microprocessor or controller with a regulated supply voltage when the input voltage is within the range required. This device can also help protect the circuits from harmful power surges and other potential overloads.

Application Fields

The FAN1084MCX is a low dropout (LDO) linear voltage regulator with an adjustable output voltage for use in DC-DC converters, power-over-ethernet (PoE), and similar applications. It offers stable input and output voltage over a wide range of input voltages and is capable of supplying up to 400mA of output current. Furthermore, the device offers low quiescent current, higher conversion efficiency, and a wide range of operating temperature. Applications of the FAN1084MCX include digital televisions, DVD players, household appliances, battery chargers, set-top boxes, and PCs.

Working Principle

The FAN1084MCX offers a low dropout voltage and utilizes a dual N-channel MOSFET pass transistor to regulate the output voltage. Upon turn on, the reference voltage is generated by an internal voltage reference. This reference voltage is then compared with the output voltage of the device using an error amplifier and fed back to the control circuit. This feedback provides the voltage regulator with accurate regulation over a wide input and output voltage range. The output voltage is then regulated by the internal pass transistor, thus maintaining the output voltage within a preset range.

The device also offers built-in soft start, thermal shutdown, and overcurrent protection which can help protect the system from accidental overloads. Furthermore, the device includes short circuit protection, reverse current protection, and reverse polarity protection to guard against external noise and ensure system reliability. The FAN1084MCX is an ideal solution for applications requiring a reliable and efficient voltage regulator for a wide range of input voltages and output currents.
