The LP2989IM-3.3/NOPB is a micropower and low-noise linear voltage regulator designed to provide a fixed output voltage of 3.3V with a maximum output current of 500 mA. It operates with an input voltage range of 2.1V to 16V and features an ultra-low dropout voltage of approximately 310 mV at full load. The device is optimized for use with ceramic output capacitors, which helps achieve very low output noise levels, typically around 18 ¬µV when an external bypass capacitor is used. This regulator has a quiescent current of less than 0.8 ¬µA in shutdown mode, making it suitable for battery-powered applications. It also includes built-in overtemperature and overcurrent protection, ensuring reliable operation under various conditions. The LP2989IM-3.3/NOPB is available in an 8-pin SOIC package and operates over a temperature range of -40¬8C to 125¬8C. Its precision output voltage accuracy is rated at 0.75% (A grade) at room temperature, making it a reliable choice for applications requiring stable voltage regulation.
