The FAN1581M12X voltage regulator is a linear, low-noise, low-current, voltage regulator and is ideal for a variety of applications, including automotive, industrial, and consumer electronics. It features an output voltage range of 0.5V to 12V and an ultra-low quiescent current of 0.1 µA. The FAN1581M12X is available in the SOT-23-5, TSOT-23-5, and USP-6 packages.

The FAN1581M12X is designed to provide accurate, low-noise, low-current voltage regulation with a wide output voltage range. Its low quiescent current ensures high efficiency and low power consumption, making it ideal for battery-powered applications. Its low-noise output and low output noise voltage of 40 µVP-P(2.4V to 5.0V) make it suitable for audio and video applications that require a low-noise supply. It offers precision, low-power output without the noise and cost associated with a switching regulator, making it a great choice for a wide range of low-power applications.

The FAN1581M12X consists of an internal voltage reference (VREF) and comparator, an error amplifier, and an internal PMOS power output transistor. The device is powered via an input pin connected to a 3V to 5.5V power supply. The voltage is regulated by comparing the voltage of the output pin to the internal reference voltage. If the output voltage is lower than the reference, the error amplifier increases the gate voltage of the PMOS transistor, which increases the output current to bring the output voltage up to the set level. If the output voltage is higher than the reference, the gate voltage of the PMOS transistor is reduced, reducing the output current, so that the output voltage is brought back to the set level. The device offers low-noise, low-current output, with an adjustable output voltage range of 0.5V to 12V.

The FAN1581M12X linear voltage regulator is ideal for applications that require low power consumption and low noise for low-voltage applications. Its wide input voltage range, low quiescent current, and low output noise make it a great choice for low-power, high-efficiency applications. It is suitable for automotive, industrial, and consumer electronics applications where accurate, low-noise, low-current voltage regulation is needed. The device is available in the SOT-23-5, TSOT-23-5, and USP-6 packages, offering a versatile solution for a wide range of applications.
