ISL9021IIBZ-T is a specialized three-terminal linear voltage regulator that comes with an enable pin, allowing the user to enable and disable the regulator without interruption of output. This feature is particularly useful for applications that need to be enabled only when voltage falls below a predetermined value or when the external supply is present. It is one of the most popular PMIC - Voltage Regulators - Linear on the market today.

The ISL9021IIBZ-T is designed for applications that utilize high current supplies. It works by using an internal voltage reference and current amplifier from the input voltage, releasing low voltage from the output. A zener diode is used to prevent the output from exceeding a configured voltage limit by shunting the excess current to ground. The enable pin is then connected to the output voltage and the current amplifier, allowing the user to enable or disable the regulator in a manner that does not affect the rest of the system.

The ISL9021IIBZ-T can be used in a variety of different applications. It is ideal for computer peripheral power supplies, automotive power supply regulation, and digital signal processor power regulation. In addition, it can be used in sensors, actuators, and transceiver power supplies. The ISL9021IIBZ-T is particularly well-suited for embedded systems and industrial control systems where maximum output accuracy is required.

The ISL9021IIBZ-T comes in an easy-to-install 3-pin TO-220 package, which allows it to fit in applications with limited space. It also works with a variety of different power sources from 3.3V to 42V and can handle input frequencies up to 200kHz. The regulator has an excellent performance-to-size ratio, making it an ideal choice for space-constrained applications.

The ISL9021IIBZ-T is highly reliable, with integrated short-circuit and over-temperature protection. It is also highly efficient, with a peak efficiency of up to 95%. The device is also RoHS-compliant and carry UL, VDE, and TUV safety approvals.

Overall, the ISL9021IIBZ-T is the perfect choice for applications that require high-precision voltage regulation in a small form factor. Its versatility and high-efficiency make it an ideal choice for a variety of applications.
