Introduction

The FAN1117AS18X is a low-cost, low-noise linear regulator that operates from a single supply voltage of either 5V or 3.3V. It is able to regulate a wide input voltage of up to 18V and provide a precise output voltage of +/-1%. This device is ideal for applications such as post-processing of digital audio, automotive switch/collection voltage supply, and pre-precision regulation of off-line input voltage.

Application Field

The FAN1117AS18X is ideally suited for use in applications that require low power, such as portable/mobile devices, automotive, and industrial control. It can be used for post-processing of digital audio, automotive switch/collection voltage supply, and pre-precision regulation of off-line input voltage. It is also used for a wide variety of industrial control applications, such as power supply for high-end telecommunication systems, automotive navigation systems, and general industrial equipment.

Working Principle

The FAN1117AS18X is a three-terminal voltage regulator that is capable of regulating output voltage from 5V to 18V. It works by adjusting the amount of current passing through an external resistive divider network, and thus can regulate output voltage to a precise value of +/- 1%. It is able to compensate for changes in input voltage, load variations, and temperature fluctuations, making it highly reliable in a wide variety of environments. The device operates by the principle of voltage regulation. A charging current is allowed to enter the device\'s output node while the output is being regulated, and the amount of current allowed to enter the output node is proportional to the amount of voltage at the input of the device. The internal temperature sensing circuitry of the FAN1117AS18X provides protection by controlling the output voltage if the device becomes too hot. In order to further protect the device and ensure the output stays within the specified range, the device has a logic input for external shutdown and two open-drain outputs for reporting over-temperature and over-current conditions.

Conclusion

The FAN1117AS18X is a low-cost, low-noise linear regulator, which can be operated from a single fifth or 3.3V power supply. It is widely used in applications that require low power, such as portable/mobile devices, automotive, and industrial control. Its ability to regulate a wide input voltage of up to 18V with a precise output of +/-1%, make it an ideal choice for post-processing of digital audio, automotive switch/collection voltage supply, and pre-precision regulation of off-line input voltage. It operates by adjusting an external resistor network and compensates for changes in input voltage, load variations, and temperature fluctuations, ensuring dependable operation in any environment. It is well-suited for use in demanding applications, such as in power supply for high-end telecommunication systems, automotive navigation systems, and general industrial equipment.
