Working Principle of ISL80102IR18Z-TK

The ISL80102IR18Z-TK is a linear voltage regulator integrated circuit (IC) working on a simple principle. It uses an internal reference voltage to compare the output voltage to its input voltage, inside of a voltage divider consisting of a series of resistors that are fed into an amplifier. When the output voltage is below the reference voltage, the output of the amplifier will drive the series of transistors connected to the output voltage. This will cause these transistors to begin drawing current to the output voltage, effectively increasing the output voltage.

When the output voltage is equal to the reference voltage, the amplifier will maintain this voltage and prevent any further increase or decrease in the output voltage. The current flowing into the output voltage will be equal to the difference between the voltage across the series of resistors and the reference voltage, multiplied by the gain of the amplifier. This means that the output voltage is determined by the reference voltage, the series resistors, and the gain of the amplifier.

The ISL80102IR18Z-TK has a low-noise, high-accuracy architecture with a high power supply rejection ratio (PSRR) of up to 100dB. This circuit also has low quiescent current, low standby current, and low ground current. It also has an adjustable output voltage, making it suitable for a range of applications.
