The ISL80136IBEAJZ-T is a linear voltage regulator belonging to a family of Power Management Integrated Circuits (PMICs). It is used for the management of power delivery and distribution to various types of electrical loads. It functions by converting input power within a specific range into a fixed value of output current or voltage for an optimum power delivery and conservation. Designed for small form factor applications (i.e. wearable technologies such as smart watch and fitness trackers, embedded systems, etc.), the ISL80136IBEAJZ-T linear voltage regulator offers high efficiency, compact size, low cost, and excellent dynamic performance.

The primary application of the ISL80136IBEAJZ-T is to provide a steady and reliable current or voltage output from a variable input voltage source. It is used to regulate the power delivery by controlling the current or voltage of the output depending on the input variations, providing a sense of stability to the system. The voltage output of this linear voltage regulator can be set through an external resistor divider, or can be adjusted via pulse-width modulation (PWM) by external circuitry. It also supports the input power of up to 8 volts.

The main feature of the ISL80136IBEAJZ-T linear voltage regulator is its integrated low drop-out/low noise regulation, which helps to ensure good voltage accuracy throughout the regulation process. The device also offers adjustable current limit with short-circuit protection, adjustable soft-start, under-voltage lockout, and low standby current consumption. All these features make it suitable for powering sensitive system components and microprocessors, as well as ensuring a continuous stable power supply.

When it comes to the working principle of the ISL80136IBEAJZ-T voltage regulator, it mainly involves an internal reference voltage generator to measure and regulate the output voltage. This internal reference can be adjusted via an external resistor divider or PWM signal from an external controller. The device also has an on-chip over-current protection that can be enabled or disabled via the EN pin. It also includes an output transistor network for impedance matching, providing enhanced power supply stability and improved transient response.

In conclusion, the ISL80136IBEAJZ-T linear voltage regulator is designed to provide regulated voltage or current output from a variable input voltage source. It offers high efficiency, excellent dynamic performance, adjustable current limit, and advanced features like adjustable soft-start and low standby current consumption. It is used in a wide range of applications, such as wearable technologies and embedded systems, and its working principle involves an internal reference voltage generator to regulate the output voltage.
