ADP165AUJZ-2.3-R7 application field and working principle

The ADP165AUJZ-2.3-R7 is a 1.2 V to 3.0 V, low drop-out linear regulator (LDO). This regulator is designed to provide a stable voltage source for a wide range of applications, including processors, storage, memory, and system peripherals. This device is specifically designed to work with low drop-out (LDO) applications, where stringent current, power supply voltage, and startup requirements need to be met.The ADP165AUJZ-2.3-R7 is designed for use in a wide variety of environments, including desktops, laptops, DAPs (Digital Audio Players), and other electronic devices. It features on-chip MOSFET technology, together with low drop-out (LDO) architecture to ensure high efficiency, low noise, and fast startup. On-chip overcurrent and overtemperature protection prevents the device from experiencing overloads or over-temperature conditions. The device\'s 8-bit I2C interface makes the level of configuration and control straightforward to achieve.The ADP165AUJZ-2.3-R7\'s architecture uses an external MOSFET as the switch control component to limit the fluctuation of output voltage. This enables the device to provide low drop-out (LDO) performance, with an output voltage range of 1.2V to 3.0V.The working principle of the device is relatively simple - the MOSFET is kept off until a voltage is applied to the reference input (VREF). The voltage at the output (VOUT) is regulated at a value equal to the reference input minus the drop-out voltage (VOL). If the drop-out voltage is exceeded, the MOSFET will remain switched ‘on’ and the output voltage will remain at its regulated voltage level.The output voltage provided by the device is adjustable within a range from 1.2V to 3.0V.The reference input voltage is adjusted with a precision resistor network. On-chip overvoltage and overtemperature protection is included to provide additional safety. The device includes a soft-start circuit and a programmable delay to prevent excessive supply current during startup.In conclusion, the ADP165AUJZ-2.3-R7 is an effective low drop-out (LDO) linear voltage regulator, offering a stable voltage supply for a wide range of devices. Its on-chip I2C interface, as well as protection circuitry, make it a reliable and efficient device ideal for a variety of applications.
