The LM1086IS-5.0/NOPB is a widely used three-terminal adjustable regulator in the linear PMIC (Power Management Integrated Circuit) voltage regulators series. It offers a wide input voltage range of up to 25V with an output voltage adjustable range of 1.2V~29V. With a unique combination of features, it performs the highest current V REG of up to 1.5A and is guaranteed not to exceed 5.0V typically. With the least dropout voltage of 1.5V at full load, it delivers unparalleled performance and reliability.

The LM1086IS-5.0/NOPB is designed for use in a wide range of applications. It is suitable for use as a power supply for high power applications such as digital audio amplifiers and for providing regulated supplies for logic circuits. It can also be used with digital processor designs and power supply sequencing from a single voltage input. Additionally, it is ideal for powering bus-powered peripherals such as USB-powered devices.

The working of the voltage regulator is fairly simple. In its most basic form, the voltage regulator consists of an LM317/LMN344 device connected to a power source, an adjustable resistor/potentiometer pair, and an output regulated voltage. The main function of the LM317/LMN344 is to compare a stable reference voltage to the voltage seen at the adjustable resistor/potentiometer. This voltage is used to control the current output of the regulator, allowing the user to adjust the output voltage by adjusting the potentiometer.

The LM1086IS-5.0/NOPB is equipped with advanced protection features that make it suitable for use in a wide range of applications. Its internal temperature protection regulates the output voltage within ±1% of nominal at any temperature and reduces the current limit until the device cools down. It also has a current-limiting feature and a reverse-polarity protection feature that prevents damage due to reverse connections of the input or the output. The device is also protected against transient-induced losses, over-voltage, excessive current, and over-temperature.

The LM1086IS-5.0/NOPB also features excellent line and load regulation specifications, due to its low output-voltage switching noise, low input voltage ripple, and low ESR capacitors. Moreover, it performs extremely well at very low loads, making it ideal for applications with very low current requirements.

In summary, the LM1086IS-5.0/NOPB is a popular three-terminal adjustable regulator in the linear PMIC voltage regulators series. It is designed for use in a wide range of applications including digital audio amplifiers, power supply sequencing, and powering USB devices. It also offers other advanced features such as temperature protection, current-limiting, reverse-polarity protection, and line and load regulation. The device is especially suitable for low current applications due to its excellent performance at very low loads.
