Working Principle

The ISL6412IR-TK is a three-terminal linear regulator with a fixed output voltage. The input voltage is applied to the input terminal and the output voltage is provided at the output terminal. The third terminal is used to control the voltage. It is connected to an adjustable voltage divider, which sets the reference voltage that determines the output voltage. When the output voltage is higher than the reference voltage, the device will force current flow from the output to the input, lowering the voltage and maintaining the set-point.

The ISL6412IR-TK features protection against short-circuits, over-current, input under-voltage, output over-voltage, and thermal protection. It is also designed for both adjustable and fixed output voltages. The adjustable version allows for a range of output voltages from 1.2V to 5.5V, while the fixed version offers a variety of fixed output voltages from 1.2V to 5.0V.

The ISL6412IR-TK is available in a variety of packages including the popular 8-pin SOIC, 10-pin MSOP, and 14-pin TSSOP packages. The device also has a wide operating temperature range of -40°C to +125°C, making it suitable for challenging industrial and automotive applications.

Conclusion

The ISL6412IR-TK is an integrated linear voltage regulator designed for a variety of applications and power systems. It is ideal for voltage regulation, voltage conditioning, and voltage limitation. It features protection against short-circuits, over-current, input under-voltage, output over-voltage, and thermal protection, and is available in a variety of packages.
