LP2989AIM-5.0 is a fixed-output low-dropout (LDO) linear voltage regulator, which provides a precise and flexible power solution for embedded systems. It is designed for use in scenarios where precise control of the output voltage is necessary and is capable of supplying up to 300mA of load current. The device is designed to operate from a 4.8V minimum input voltage and has a low typically drop-out voltage of 75mV at 150mA of load current. The LP2989AIM-5.0 features an output voltage accuracy of ± 0.5% and an adjustable output voltage range of 1.2V to 5.5V. This makes the device suitable for applications that require a high level of accuracy in the output voltage, such as microprocessors, digital signal processors, embedded systems, and other applications. The device is packaged in an easy-to-use five-pin SOT- package and comes in EIAJ (9’) package sizes.The LP2989AIM-5.0 works on the principle of a voltage reference. The device relies on a precision voltage reference, a temperature-sensing element, and an error amplifier for setting the output voltage. The reference voltage is set through the adjustment pin and is compared with the voltage divider which is connected to a voltage-sensing element. The voltage at the divider is compared to the reference voltage by the error amplifier and the output is adjusted accordingly. The output voltage is also subject to a temperature coefficient which is adjustable through the adjustment pin.The LP2989AIM-5.0 features current limiting and thermal protection, along with overload and short circuit protection. The current-limiting feature prevents excessive current from flowing in the output stage and the device will automatically shut down in the event of an over-temperature situation. The overload protection ensures that the output does not exceed the programmed value and will shut the device off in the event of a short-circuit.The LP2989AIM-5.0 devices are suitable for a wide range of applications such as microprocessors, digital signal processors, embedded systems, and other applications that require precise control of the output voltage. The device can also be used in automotive, industrial, and consumer applications. The device is also RoHS compliant, making it suitable for use in green applications.In conclusion, the LP2989AIM-5.0 is an ideal solution for applications with precise output voltage control requirements such as microprocessors and digital signal processors. It features an adjustable output voltage range of 1.2V to 5.5V and an output voltage accuracy of ± 0.5%, and is packaged in an easy-to-use five-pin SOT- package that comes in EIAJ (9’) package sizes. The device also offers protection features such as current limiting and thermal protection, overload and short circuit protection, and is RoHS compliant.
