FAN1086M25 Application Field and Working Principle

PMIC - Voltage Regulators - LinearThe FAN1086M25 is a PMIC (Power Management Integrated Circuit) designed for use in a variety of applications requiring voltage regulation. It is a linear regulator, which means that it operates by altering the impedance of an imaginary circuit, known as a feedback loop, to control the output voltage at a given level. The output voltage is determined by varying the feedback loop\'s resistance and impedance, with the control being provided by an internal voltage reference and an external resistance network. The FAN1086M25 is designed specifically for use with low-current, low-voltage applications, and can be used to regulate output voltages from 0.8V to 5.5V.The FAN1086M25 is suitable for use in a wide range of applications, including linear regulators in computers, telecommunications, and automotive electronics. It is particularly effective when used to provide constant and stable voltage levels for circuits such as voltage regulators, onboard power supplies, or power converters. Additionally, the FAN1086M25 offers low output noise and is capable of output current up to 5.5A. The FAN1086M25 includes two internal MOSFET transistors, one N-channel and one P-channel, which are responsible for the regulation of incoming and outgoing electrical currents. The P-channel MOSFET, in particular, is responsible for ensuring proper voltage levels at the output of the circuit. The P-channel MOSFET directs the incoming current to the output, depending on the logic level of the voltage reference. If the voltage reference is low, the current is directed to the output, and if the voltage reference is high, the current is directed away from the output and back to the source. This allows for precise regulation at the output, relative to the incoming current.The FAN1086M25 also features a slew-rate-limiting control, which modulates the speed at which the output voltage changes and can be used to reduce the effect of output voltage glitches due to transient currents. The current limit and thermal shutdown features are also included in the FAN1086M25, offering additional protection against damages arising from excessive levels of current or high temperatures.Overall, the FAN1086M25 is a linear voltage regulator well-suited for use in a variety of low-current, low-voltage applications. It features a wide input voltage range of 4.5V to 5.5V, a low quiescent current of 6.0mA, a wide output voltage range of 0.8V to 5.5V, and an operating temperature range of -55 to 125 degrees Celsius. Furthermore, the device is designed to provide optimal stability and protection against over-current and high temperatures, offering reliability and cost-effectiveness for a wide range of applications.
