Features of LX8586A-00CP

The LX8586A-00CP is a low-dropout (LDO) linear voltage regulator with a wide input voltage range from 3V to 30V and an adjustable output voltage range from 0.8V to 40V. It is capable of supplying up to 1.8A of current and can operate at temperatures from -40ºC to +125ºC, making it suitable for a wide range of applications. The device is also equipped with a disable pin, which allows the regulator to be shut off when not in use and helps conserve power. Moreover, it features a low quiescent current (IQ) of only 15 µA and a low output noise of 35 µVrms, ensuring that the output voltage remains stable and reliable.

Working Principle of LX8586A-00CP

The LX8586A-00CP uses a switching regulator mode operation to provide a stable, efficient, and low-noise output voltage. The regulator is designed with a voltage reference, an error amplifier, a series pass transistors, and a set of current limit resistors, all of which play an important role in regulating the output voltage. This design enables the device to accurately regulate the output voltage within a range of 0.8V to 40V.

When an input voltage is applied, the error amplifier compares the reference voltage and the actual output voltage, generated by the series pass transistor. When the two don’t match, the output voltage changes until they reach the same level. This ensures that the output voltage remains stable, independent of any load variation or line voltage changes. Also, current limiting helps prevent any excessive current from damaging the device.

Conclusion

The LX8586A-00CP is a versatile linear voltage regulator from Diodes Incorporated. It is suitable for a variety of applications, ranging from medical devices to consumer electronics, and offers a wide range of features such as low quiescent current, wide input voltage range, and low output noise. The device uses a switching regulator mode operation that allows it to accurately regulate the output voltage within a range of 0.8V to 40V.
