The FAN1582D12X provides excellent ripple rejection, making it ideal for sensitive electronic applications.

Application Field

The FAN1582D12X is perfect for powering low power, low noise applications that require high accuracy and low dropout voltage. It is widely used in personal computers, notebooks, PC-related products, cell phones, tablet PCs, communication systems, light emitting diode (LED) lighting, audio systems, and many other consumer audio-visual products. The FAN1582D12X is commonly employed in handheld, portable and battery-powered electronics due to its low dropout voltage and tiny package.

Working Principle

The FAN1582D12X is an integrated circuit, a type of Linear Voltage Regulator. It is a three-terminal device, meaning it has an input terminal (Vin), an output terminal (Vout) and a ground terminal. Typically, the FAN1582D12X requires a minimum input voltage of 2.0V in order to generate a regulated voltage output, and the maximum input voltage is 10V. The output voltage of the FAN1582D12X is set by two resistors, R1 and R2, which form a voltage divider. R1 is the controlling resistor and R2 is a reference or feedback resistor. The FAN1582D12X uses feedback to maintain a constant regulated output voltage, regardless of changes in input voltage or load current. When the input voltage is higher than the output voltage, the FAN1582D12X allows a current to flow, which is converted into heat. This process is known as linear regulation, and it maintains the output voltage at a constant level. The FAN1582D12X features a low quiescent current and low dropout voltage, making it perfect for battery-operated devices.

Conclusion

As a summary, the FAN1582D12X is a High Accuracy Linear Voltage Regulator manufactured by Fairchild Semiconductor. It is a three-terminal device with an input voltage range of 2.0V to 10V, and an output voltage range of 1.5V to 8.0V. The FAN1582D12X is commonly used in a variety of handheld, portable and battery-powered electronics due to its low dropout voltage and tiny package. Additionally, the FAN1582D12X features a low quiescent current and excellent ripple rejection which is vital for sensitive electronic devices.
