Texas Instruments High-Performance Analog 3V 500mA 16V SOIC LDO Voltage Regulator IC LP2989IMX-3.0

The LP2989IMX-3.0 is a micropower and low-noise linear voltage regulator designed to provide a fixed output voltage of 3.0 V with a maximum output current of 500 mA. It operates with an input voltage range of 2.1 V to 16 V 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 includes built-in overtemperature and overcurrent protection, ensuring reliable operation under various conditions. It has a quiescent current of less than 0.8 µA in shutdown mode, making it suitable for battery-powered applications. The LP2989IMX-3.0 is available in multiple package options, including 8-pin SOIC and VSSOP, facilitating integration into various designs. 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.
