FAN1117AD18X is a type of linear voltage regulator, which is produced by Fairchild semiconductor and specified to have a maximum output current of up to 1.5 A. FAN1117AD18X is mainly used in the field of computer and mobile phone, such as laptop, tablet and mobile phone. It is also suitable for variety of other applications.

The working principle of the FAN1117AD18X is based on the fact that as the input voltage remains constant, the output voltage of the linear voltage regulator is directly proportional to the voltage drop across its internal components. Specifically, FAN1117AD18X uses two different transistors; a N-MOSFET as the regulating transistor and a P-MOSFET that is used as a switch. When the load is connected to the regulated voltage the N-MOSFET is turned on, which causes a current to flow through the internal components to the load. This causes the voltage drop to increase and thus, the output voltage is reduced according to the voltage drop across the internal components.

In addition to its main purpose as a linear voltage regulator, FAN1117AD18X has also other features such as over-current protection and thermal shutdown. The over-current protection feature will protect the regulator from excessive current. When the output current of the FAN1117AD18X exceeds its maximum rating the over-current feature will be triggered, causing the regulator to shut off, thus protecting the system from further damage. The thermal shutdown feature protects the regulator from excessive thermal performance. When the temperature of the regulator exceeds its maximum rating, the thermal shutdown feature is triggered, causing the regulator to shut off as well. This is done to prevent any further damage from happening to the regulator.

FAN1117AD18X is a highly efficient linear voltage regulator that can deliver up to 1.5 amps of output current. It is designed to be used in applications such as computer and mobile phone, such as laptop, tablet and mobile phone. It is also suitable for a variety of other applications. Its main features are the over-current protection, thermal shutdown and its internal components that enable it to deliver a constant output voltage even when the input voltage changes.
