LM1086IS-1.8 voltage regulator is one of the most commonly used linear voltage regulators. It is a chip featuring low distortion, low noise, low dropout voltage and low quiescent current, and it is capable of delivering up to 1.5A output current. It is basically a 3-terminal device configured as a adjustable shunt regulator, which can be used to regulate the output voltage from 1.25V to 28V, and the adjustment allows a maximum output voltage tolerance of 1%.

This voltage regulator is very popular in almost all types of electronic applications for the purpose of regulating and controlling the output voltage levels. It is commonly used in applications like power supplies, audio and video amplifiers, battery chargers, motor drives, test instruments, medical electronics, consumer electronics and a variety of alternative power sources. In addition to this, the LM1086IS-1.8 is also widely used in smaller voltage regulator projects since its small size allows it to fit in space-restricted applications.

The LM1086IS-1.8 works on the principle of shunt regulator. In a shunt regulator, the regulator consists of a series of diodes that are wired in parallel ways.The total voltage applied to the shunt regulator is divided among the different diodes. The output voltage is obtained by subtracting the voltage drop of the series diodes from the input voltage. This is then compared to the voltage reference in the circuit, and the result of this comparison adjusts the output of the shunt regulator to a value that is equal to the reference voltage.

The LM1086IS-1.8 voltage regulator is designed to deliver current up to 1.5A with very low dropout voltage of less than 0.5V. It is capable of operating as either an adjustable or a fixed-linear voltage regulator. The adjustable output voltage range is from 1.25V to 28V, and the fixed output voltage can be preset using the onboard potentiometer. It features the low quiescent current of only 1.5mA and very low noise and distortion of 25μV and 1μV respectively.

The LM1086IS-1.8 is a versatile regulator with high accuracy, and it is also very reliable. It has an extended operating temperature of -40°C to 85°C and is packaged in a small SOT-223 package. It is also very easy to use and is available in a simple 3 pin configuration. The LM1086IS-1.8 can be powered by either a single or a dual supply and can be used in a wide range of applications.

This voltage regulator is a great choice for various high-current applications that require low-noise, low-dropout and high accuracy. It provides excellent performance with very low power input and very low quiescent current. It also supports a wide input voltage range, which makes it suitable for both single-supply and dual-supply applications. All these features make the LM1086IS-1.8 an ideal linear voltage regulator for many applications.
